A circularly permuted subfamily of the Ras GTPases; Nucleostemin (NS) is a nucleolar protein that functions as a regulator of cell growth and proliferation in stem cells and in several types of cancer cells, but is not expressed in the differentiated cells of most mammalian adult tissues. NS shuttles between the nucleolus and nucleoplasm bidirectionally at a rate that is fast and independent of cell type. Lowering GTP levels decreases the nucleolar retention of NS, and expression of NS is abruptly down-regulated during differentiation prior to terminal cell division. Found only in eukaryotes, NS consists of an N-terminal basic domain, a coiled-coil domain, a GTP-binding domain, an intermediate domain, and a C-terminal acidic domain. Experimental evidence indicates that NS uses its GTP-binding property as a molecular switch to control the transition between the nucleolus and nucleoplasm, and this process involves interaction between the basic, GTP-binding, and intermediate domains of the protein.

Rat sarcoma (Ras)-like superfamily of small guanosine triphosphatases (GTPases); Ras-like GTPase superfamily. The Ras-like superfamily of small GTPases consists of several families with an extremely high degree of structural and functional similarity. The Ras superfamily is divided into at least four families in eukaryotes: the Ras, Rho, Rab, and Sar1/Arf families. This superfamily also includes proteins like the GTP translation factors, Era-like GTPases, and G-alpha chain of the heterotrimeric G proteins. Members of the Ras superfamily regulate a wide variety of cellular functions: the Ras family regulates gene expression, the Rho family regulates cytoskeletal reorganization and gene expression, the Rab and Sar1/Arf families regulate vesicle trafficking, and the Ran family regulates nucleocytoplasmic transport and microtubule organization. The GTP translation factor family regulates initiation, elongation, termination, and release in translation, and the Era-like GTPase family regulates cell division, sporulation, and DNA replication. Members of the Ras superfamily are identified by the GTP binding site, which is made up of five characteristic sequence motifs, and the switch I and switch II regions.

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: 50.39 E-value: 1.16e-06

387-420 | 1.54e-05 | ||||||
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. EngA and its orthologs are composed of two GTPase domains and, 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.

Nucleolar GTP-binding protein (NOG); NOG1 is a nucleolar GTP-binding protein present in eukaryotes ranging from trypanosomes to humans. NOG1 is functionally linked to ribosome biogenesis and found in association with the nuclear pore complexes and identified in many preribosomal complexes. Thus, defects in NOG1 can lead to defects in 60S biogenesis. The S. cerevisiae NOG1 gene is essential for cell viability, and mutations in the predicted G motifs abrogate function. It is a member of the ODN family of GTP-binding proteins that also includes the bacterial Obg and DRG proteins. Pssm-ID: 206684 [Multi-domain] Cd Length: 167 Bit Score: 39.85 E-value: 1.47e-03

trmE is a tRNA modification GTPase; TrmE (MnmE, ThdF, MSS1) is a 3-domain protein found in bacteria and eukaryotes. 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.

Developmentally Regulated GTP-binding protein (DRG); The developmentally regulated GTP-binding protein (DRG) subfamily is an uncharacterized member of the Obg family, an evolutionary branch of GTPase superfamily proteins. GTPases act as molecular switches regulating diverse cellular processes. DRG2 and DRG1 comprise the DRG subfamily in eukaryotes. In view of their widespread expression in various tissues and high conservation among distantly related species in eukaryotes and archaea, DRG proteins may regulate fundamental cellular processes. It is proposed that the DRG subfamily proteins play their physiological roles through RNA binding. Pssm-ID: 206683 [Multi-domain] Cd Length: 233 Bit Score: 39.45 E-value: 3.26e-03

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. EngA and its orthologs are composed of two GTPase domains and, 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.

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.

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: 38.57 E-value: 4.55e-03
