N-terminal domain of TrmE, a tRNA modification GTPase; This family contains the N-terminal domain of TrmE (also known as MnmE, ThdF, MSS1), a guanine nucleotide-binding protein conserved in all three kingdoms of life. It is involved in the modification of uridine bases (U34) at the first anticodon (wobble) position of tRNAs decoding two-family box triplets. TrmE is a three-domain protein comprising an N-terminal alpha/beta domain, a helical domain, and the GTPase domain which is nested within the helical domain. The N-terminal domain induces dimerization for self-assembly and is topologically homologous to the tetrahydrofolate (THF)-binding domain of N,N-dimethylglycine oxidase (DMGO). However, the THF-binding site in DMGO is encoded on a single polypeptide, while homodimerization would be required to create a similar THF-binding site in TrmE. Dimerization also creates a second, symmetry-related THF-binding site. Biochemical and structural studies show that TrmE indeed binds formyl-THF. A cysteine residue, necessary for modification of U34, is located close to the C1-group donor 5-formyl-tetrahydrofolate, suggesting a direct role of TrmE in the modification analogous to DNA modification enzymes.

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.

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.

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.

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.

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.

208-270 | 3.89e-06 | ||||||||
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.

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: 44.86 E-value: 2.70e-05
