Mutations in this gene are pleiotropic, but it appears that effects on cellular functions such as chromosome partition may be secondary to the effect on ribosome structure. Recent work done in Vibrio cholerae shows an essential role in the stringent response, in which RelA-dependent ability to synthesize the alarmone ppGpp is required for deletion of this GTPase to be lethal.

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.

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: 101.85 E-value: 2.32e-25

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.

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.

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.

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.

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.

YihA (EngB) GTPase family; The YihA (EngB) subfamily of GTPases is typified by the E. coli YihA, an essential protein involved in cell division control. YihA and its orthologs are small proteins that typically contain less than 200 amino acid residues and consists of the GTPase domain only (some of the eukaryotic homologs contain an N-terminal extension of about 120 residues that might be involved in organellar targeting). Homologs of yihA are found in most Gram-positive and Gram-negative pathogenic bacteria, with the exception of Mycobacterium tuberculosis. The broad-spectrum nature of YihA and its essentiality for cell viability in bacteria make it an attractive antibacterial target.
