EngA2 GTPase contains the second domain of EngA; This EngA2 subfamily CD represents the second GTPase domain of EngA and its orthologs, which are composed of two adjacent GTPase domains. Since the sequences of the two domains are more similar to each other than to other GTPases, it is likely that an ancient gene duplication, rather than a fusion of evolutionarily distinct GTPases, gave rise to this family. Although the exact function of these proteins has not been elucidated, studies have revealed that the E. coli EngA homolog, Der, and Neisseria gonorrhoeae EngA are essential for cell viability. A recent report suggests that E. coli Der functions in ribosome assembly and stability. Pssm-ID: 206682 [Multi-domain] Cd Length: 174 Bit Score: 284.71 E-value: 1.25e-95

KH-domain-like of EngA bacterial GTPase enzymes, C-terminal; The KH-like domain at the C-terminus of the EngA subfamily of essential bacterial GTPases has a unique domain structure position. The two adjacent GTPase domains (GD1 and GD2), two domains of family MMR_HSR1, pfam01926, pack at either side of the C-terminal domain. This C-terminal domain resembles a KH domain but is missing the distinctive RNA recognition elements. Conserved motifs of the nucleotide binding site of GD1 are integral parts of the GD1-KH domain interface, suggesting the interactions between these two domains are directly influenced by the GTP/GDP cycling of the protein. In contrast, the GD2-KH domain interface is distal to the GDP binding site of GD2. This family has not been added to the KH clan since SCOP classifies it separately due to its missing the key KH motif/fold.

It controls modification of the uridine at the wobble position (U34) of tRNAs that read codons ending with A or G in the mixed codon family boxes. TrmE contains a GTPase domain that forms a canonical Ras-like fold. It functions a molecular switch GTPase, and apparently uses a conformational change associated with GTP hydrolysis to promote the tRNA modification reaction, in which the conserved cysteine in the C-terminal domain is thought to function as a catalytic residue. In bacteria that are able to survive in extremely low pH conditions, TrmE regulates glutamate-dependent acid resistance.

E. coli Ras-like protein (Era) is a multifunctional GTPase; Era (E. coli Ras-like protein) is a multifunctional GTPase found in all bacteria except some eubacteria. It binds to the 16S ribosomal RNA (rRNA) of the 30S subunit and appears to play a role in the assembly of the 30S subunit, possibly by chaperoning the 16S rRNA. It also contacts several assembly elements of the 30S subunit. Era couples cell growth with cytokinesis and plays a role in cell division and energy metabolism. Homologs have also been found in eukaryotes. Era contains two domains: the N-terminal GTPase domain and a C-terminal domain KH domain that is critical for RNA binding. Both domains are important for Era function. Era is functionally able to compensate for deletion of RbfA, a cold-shock adaptation protein that is required for efficient processing of the 16S rRNA.

E. coli Ras-like protein (Era)-like GTPase; The Era (E. coli Ras-like protein)-like family includes several distinct subfamilies (TrmE/ThdF, FeoB, YihA (EngB), Era, and EngA/YfgK) that generally show sequence conservation in the region between the Walker A and B motifs (G1 and G3 box motifs), to the exclusion of other GTPases. TrmE is ubiquitous in bacteria and is a widespread mitochondrial protein in eukaryotes, but is absent from archaea. The yeast member of TrmE family, MSS1, is involved in mitochondrial translation; bacterial members are often present in translation-related operons. FeoB represents an unusual adaptation of GTPases for high-affinity iron (II) transport. YihA (EngB) family of GTPases is typified by the E. coli YihA, which is an essential protein involved in cell division control. Era is characterized by a distinct derivative of the KH domain (the pseudo-KH domain) which is located C-terminal to the GTPase domain.

Four of these groups (Obg, DRG, YyaF/YchF, and Ygr210) are characterized by a distinct glycine-rich motif immediately following the Walker B motif (G3 box). Obg/CgtA is an essential gene that is involved in the initiation of sporulation and DNA replication in the bacteria Caulobacter and Bacillus, but its exact molecular role is unknown. Furthermore, several OBG family members possess a C-terminal RNA-binding domain, the TGS domain, which is also present in threonyl-tRNA synthetase and in bacterial guanosine polyphosphatase SpoT. Nog1 is a nucleolar protein that might function in ribosome assembly.

LepA is ubiquitous in bacteria and eukaryota (e.g. yeast GUF1p), but is missing from archaea. This pattern of phyletic distribution suggests that LepA evolved through a duplication of the EF-G gene in bacteria, followed by early transfer into the eukaryotic lineage, most likely from the promitochondrial endosymbiont. Yeast GUF1p is not essential and mutant cells did not reveal any marked phenotype. Pssm-ID: 206677 [Multi-domain] Cd Length: 179 Bit Score: 55.62 E-value: 4.98e-09

Elongation factor G (EF-G) family; Translocation is mediated by EF-G (also called translocase). The structure of EF-G closely resembles that of the complex between EF-Tu and tRNA. This is an example of molecular mimicry; a protein domain evolved so that it mimics the shape of a tRNA molecule. EF-G in the GTP form binds to the ribosome, primarily through the interaction of its EF-Tu-like domain with the 50S subunit. The binding of EF-G to the ribosome in this manner stimulates the GTPase activity of EF-G. On GTP hydrolysis, EF-G undergoes a conformational change that forces its arm deeper into the A site on the 30S subunit. To accommodate this domain, the peptidyl-tRNA in the A site moves to the P site, carrying the mRNA and the deacylated tRNA with it. The ribosome may be prepared for these rearrangements by the initial binding of EF-G as well. The dissociation of EF-G leaves the ribosome ready to accept the next aminoacyl-tRNA into the A site. This group contains only bacterial members. Pssm-ID: 206733 [Multi-domain] Cd Length: 268 Bit Score: 50.28 E-value: 8.37e-07

Obg-like family of GTPases consist of five subfamilies: Obg, DRG, YyaF/YchF, Ygr210, and NOG1; The Obg-like subfamily consists of five well-delimited, ancient subfamilies, namely Obg, DRG, YyaF/YchF, Ygr210, and NOG1. Four of these groups (Obg, DRG, YyaF/YchF, and Ygr210) are characterized by a distinct glycine-rich motif immediately following the Walker B motif (G3 box). Obg/CgtA is an essential gene that is involved in the initiation of sporulation and DNA replication in the bacteria Caulobacter and Bacillus, but its exact molecular role is unknown. Furthermore, several OBG family members possess a C-terminal RNA-binding domain, the TGS domain, which is also present in threonyl-tRNA synthetase and in bacterial guanosine polyphosphatase SpoT. Nog1 is a nucleolar protein that might function in ribosome assembly. The DRG and Nog1 subfamilies are ubiquitous in archaea and eukaryotes, the Ygr210 subfamily is present in archaea and fungi, and the Obg and YyaF/YchF subfamilies are ubiquitous in bacteria and eukaryotes. The Obg/Nog1 and DRG subfamilies appear to form one major branch of the Obg family and the Ygr210 and YchF subfamilies form another branch. No GEFs, GAPs, or GDIs for Obg have been identified.

Tyrosine phosphorylated protein A (TypA)/BipA family belongs to ribosome-binding GTPases; BipA is a protein belonging to the ribosome-binding family of GTPases and is widely distributed in bacteria and plants. BipA was originally described as a protein that is induced in Salmonella typhimurium after exposure to bactericidal/permeability-inducing protein (a cationic antimicrobial protein produced by neutrophils), and has since been identified in E. coli as well. The properties thus far described for BipA are related to its role in the process of pathogenesis by enteropathogenic E. coli. It appears to be involved in the regulation of several processes important for infection, including rearrangements of the cytoskeleton of the host, bacterial resistance to host defense peptides, flagellum-mediated cell motility, and expression of K5 capsular genes. It has been proposed that BipA may utilize a novel mechanism to regulate the expression of target genes. In addition, BipA from enteropathogenic E. coli has been shown to be phosphorylated on a tyrosine residue, while BipA from Salmonella and from E. coli K12 strains is not phosphorylated under the conditions assayed. The phosphorylation apparently modifies the rate of nucleotide hydrolysis, with the phosphorylated form showing greatly increased GTPase activity.

Dynamin-like protein including dynamins, mitofusins, and guanylate-binding proteins; The dynamin family of large mechanochemical GTPases includes the classical dynamins and dynamin-like proteins (DLPs) that are found throughout the Eukarya. This family also includes bacterial DLPs. These proteins catalyze membrane fission during clathrin-mediated endocytosis. Dynamin consists of five domains; an N-terminal G domain that binds and hydrolyzes GTP, a middle domain (MD) involved in self-assembly and oligomerization, a pleckstrin homology (PH) domain responsible for interactions with the plasma membrane, GED, which is also involved in self-assembly, and a proline arginine rich domain (PRD) that interacts with SH3 domains on accessory proteins. To date, three vertebrate dynamin genes have been identified; dynamin 1, which is brain specific, mediates uptake of synaptic vesicles in presynaptic terminals; dynamin-2 is expressed ubiquitously and similarly participates in membrane fission; mutations in the MD, PH and GED domains of dynamin 2 have been linked to human diseases such as Charcot-Marie-Tooth peripheral neuropathy and rare forms of centronuclear myopathy. Dynamin 3 participates in megakaryocyte progenitor amplification, and is also involved in cytoplasmic enlargement and the formation of the demarcation membrane system. This family also includes mitofusins (MFN1 and MFN2 in mammals) that are involved in mitochondrial fusion. Dynamin oligomerizes into helical structures around the neck of budding vesicles in a GTP hydrolysis-dependent manner. Pssm-ID: 206739 [Multi-domain] Cd Length: 180 Bit Score: 47.54 E-value: 2.71e-06

The Toc complex at the outer envelope membrane of chloroplasts is a molecular machine of ~500 kDa that contains a single Toc159 protein, four Toc75 molecules, and four or five copies of Toc34. Toc64 and Toc12 are associated with the translocon, but do not appear to be part of the core complex. The Toc translocon initiates the import of nuclear-encoded preproteins from the cytosol into the organelle. Toc34 and Toc159 are both GTPases, while Toc75 is a beta-barrel integral membrane protein. Toc159 is equally distributed between a soluble cytoplasmic form and a membrane-inserted form, suggesting that assembly of the Toc complex is dynamic.

The members of this subfamily are involved in endocytosis and endocytic-sorting pathways. In mammals, Rab5 GTPases localize to early endosomes and regulate fusion of clathrin-coated vesicles to early endosomes and fusion between early endosomes. In yeast, Ypt51p family members similarly regulate membrane trafficking through prevacuolar compartments. GTPase activating proteins (GAPs) interact with GTP-bound Rab and accelerate the hydrolysis of GTP to GDP. Guanine nucleotide exchange factors (GEFs) interact with GDP-bound Rabs to promote the formation of the GTP-bound state. Rabs are further regulated by guanine nucleotide dissociation inhibitors (GDIs), which facilitate Rab recycling by masking C-terminal lipid binding and promoting cytosolic localization. Most Rab GTPases contain a lipid modification site at the C-terminus, with sequence motifs CC, CXC, or CCX. Lipid binding is essential for membrane attachment, a key feature of most Rab proteins.

Ras proteins regulate cell growth, proliferation and differentiation. Ras is activated by guanine nucleotide exchange factors (GEFs) that release GDP and allow GTP binding. Many RasGEFs have been identified. These are sequestered in the cytosol until activation by growth factors triggers recruitment to the plasma membrane or Golgi, where the GEF colocalizes with Ras. Active GTP-bound Ras interacts with several effector proteins: among the best characterized are the Raf kinases, phosphatidylinositol 3-kinase (PI3K), RalGEFs and NORE/MST1. Most Ras proteins contain a lipid modification site at the C-terminus, with a typical sequence motif CaaX, where a = an aliphatic amino acid and X = any amino acid.

Initiation Factor 2 (IF2)/ eukaryotic Initiation Factor 5B (eIF5B) family; IF2/eIF5B contribute to ribosomal subunit joining and function as GTPases that are maximally activated by the presence of both ribosomal subunits. As seen in other GTPases, IF2/IF5B undergoes conformational changes between its GTP- and GDP-bound states. Eukaryotic IF2/eIF5Bs possess three characteristic segments, including a divergent N-terminal region followed by conserved central and C-terminal segments. This core region is conserved among all known eukaryotic and archaeal IF2/eIF5Bs and eubacterial IF2s. Pssm-ID: 206674 [Multi-domain] Cd Length: 169 Bit Score: 39.76 E-value: 8.51e-04

Obg GTPase; The Obg nucleotide binding protein subfamily has been implicated in stress response, chromosome partitioning, replication initiation, mycelium development, and sporulation. Obg proteins are among a large group of GTP binding proteins conserved from bacteria to humans. The E. coli homolog, ObgE is believed to function in ribosomal biogenesis. Members of the subfamily contain two equally and highly conserved domains, a C-terminal GTP binding domain and an N-terminal glycine-rich domain.

Circularly permuted YqeH GTPase; YqeH is an essential GTP-binding protein. Depletion of YqeH induces an excess initiation of DNA replication, suggesting that it negatively controls initiation of chromosome replication. The YqeH subfamily is common in eukaryotes and sporadically present in bacteria with probable acquisition by plants from chloroplasts. Proteins of the YqeH family contain all sequence motifs typical of the vast class of P-loop-containing GTPases, but show a circular permutation, with a G4-G1-G3 pattern of motifs as opposed to the regular G1-G3-G4 pattern seen in most GTPases.

Ras of Complex, Roc, domain of DAPkinase; Roc, or Ras of Complex, proteins are mitochondrial Rho proteins (Miro-1, and Miro-2) and atypical Rho GTPases. Full-length proteins have a unique domain organization, with tandem GTP-binding domains and two EF hand domains (pfam00036) that may bind calcium. They are also larger than classical small GTPases. It has been proposed that they are involved in mitochondrial homeostasis and apoptosis. Pssm-ID: 462490 [Multi-domain] Cd Length: 114 Bit Score: 38.26 E-value: 1.35e-03

Ribosomal interacting GTPase YjeQ/EngC, a circularly permuted subfamily of the Ras GTPases; YjeQ (YloQ in Bacillus subtilis) is a ribosomal small subunit-dependent GTPase; hence also known as RsgA. YjeQ is a late-stage ribosomal biogenesis factor involved in the 30S subunit maturation, and it represents a protein family whose members are broadly conserved in bacteria and have been shown to be essential to the growth of E. coli and B. subtilis. Proteins of the YjeQ family contain all sequence motifs typical of the vast class of P-loop-containing GTPases, but show a circular permutation, with a G4-G1-G3 pattern of motifs as opposed to the regular G1-G3-G4 pattern seen in most GTPases. All YjeQ family proteins display a unique domain architecture, which includes an N-terminal OB-fold RNA-binding domain, the central permuted GTPase domain, and a zinc knuckle-like C-terminal cysteine domain.

YchF GTPase; YchF is a member of the Obg family, which includes four other subfamilies of GTPases: Obg, DRG, Ygr210, and NOG1. Obg is an essential gene that is involved in DNA replication in C. crescentus and Streptomyces griseus and is associated with the ribosome. Several members of the family, including YchF, possess the TGS domain related to the RNA-binding proteins. Experimental data and genomic analysis suggest that YchF may be part of a nucleoprotein complex and may function as a GTP-dependent translational factor.

Elongation factor G (EF-G) family; Translocation is mediated by EF-G (also called translocase). The structure of EF-G closely resembles that of the complex between EF-Tu and tRNA. This is an example of molecular mimicry; a protein domain evolved so that it mimics the shape of a tRNA molecule. EF-G in the GTP form binds to the ribosome, primarily through the interaction of its EF-Tu-like domain with the 50S subunit. The binding of EF-G to the ribosome in this manner stimulates the GTPase activity of EF-G. On GTP hydrolysis, EF-G undergoes a conformational change that forces its arm deeper into the A site on the 30S subunit. To accommodate this domain, the peptidyl-tRNA in the A site moves to the P site, carrying the mRNA and the deacylated tRNA with it. The ribosome may be prepared for these rearrangements by the initial binding of EF-G as well. The dissociation of EF-G leaves the ribosome ready to accept the next aminoacyl-tRNA into the A site. This group contains only bacterial members. Pssm-ID: 206733 [Multi-domain] Cd Length: 268 Bit Score: 40.27 E-value: 1.62e-03

Rab GTPase family 21 (Rab21); The localization and function of Rab21 are not clearly defined, with conflicting data reported. Rab21 has been reported to localize in the ER in human intestinal epithelial cells, with partial colocalization with alpha-glucosidase, a late endosomal/lysosomal marker. More recently, Rab21 was shown to colocalize with and affect the morphology of early endosomes. In Dictyostelium, GTP-bound Rab21, together with two novel LIM domain proteins, LimF and ChLim, has been shown to regulate phagocytosis. GTPase activating proteins (GAPs) interact with GTP-bound Rab and accelerate the hydrolysis of GTP to GDP. Guanine nucleotide exchange factors (GEFs) interact with GDP-bound Rabs to promote the formation of the GTP-bound state. Rabs are further regulated by guanine nucleotide dissociation inhibitors (GDIs), which facilitate Rab recycling by masking C-terminal lipid binding and promoting cytosolic localization. Most Rab GTPases contain a lipid modification site at the C-terminus, with sequence motifs CC, CXC, or CCX. Lipid binding is essential for membrane attachment, a key feature of most Rab proteins. Due to the presence of truncated sequences in this CD, the lipid modification site is not available for annotation. Pssm-ID: 133323 [Multi-domain] Cd Length: 162 Bit Score: 37.59 E-value: 4.66e-03

Translocon at the Outer-envelope membrane of Chloroplasts 34-like (Toc34-like); The Toc34-like (Translocon at the Outer-envelope membrane of Chloroplasts) family contains several Toc proteins, including Toc34, Toc33, Toc120, Toc159, Toc86, Toc125, and Toc90. The Toc complex at the outer envelope membrane of chloroplasts is a molecular machine of ~500 kDa that contains a single Toc159 protein, four Toc75 molecules, and four or five copies of Toc34. Toc64 and Toc12 are associated with the translocon, but do not appear to be part of the core complex. The Toc translocon initiates the import of nuclear-encoded preproteins from the cytosol into the organelle. Toc34 and Toc159 are both GTPases, while Toc75 is a beta-barrel integral membrane protein. Toc159 is equally distributed between a soluble cytoplasmic form and a membrane-inserted form, suggesting that assembly of the Toc complex is dynamic. Toc34 and Toc75 act sequentially to mediate docking and insertion of Toc159 resulting in assembly of the functional translocon. Pssm-ID: 206652 Cd Length: 248 Bit Score: 37.68 E-value: 9.16e-03
