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.

type II K-homology (KH) RNA-binding domain found in GTPase Era and similar proteins; GTPase Era, also called ERA or GTP-binding protein Era, is an essential GTPase that binds both GDP and GTP, with nucleotide exchange occurring in the order of seconds whereas hydrolysis occurs in the order of minutes. It plays a role in numerous processes, including cell cycle regulation, energy metabolism, as a chaperone for 16S rRNA processing, and 30S ribosomal subunit biogenesis. Its presence in the 30S subunit may prevent translation initiation. GTPase Era may also be critical for maintaining cell growth and cell division rates. Members of this family contain only one canonical type II K-homology (KH) domain that has the signature motif GXXG (where X represents any amino acid).

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.

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.

AvrRpt2-Induced Gene 1 (AIG1); This group represents Arabidoposis protein AIG1 (avrRpt2-induced gene 1) that appears to be involved in plant resistance to bacteria. The Arabidopsis disease resistance gene RPS2 is involved in recognition of bacterial pathogens carrying the avirulence gene avrRpt2. AIG1 exhibits RPS2- and avrRpt1-dependent induction early after infection with Pseudomonas syringae carrying avrRpt2. This subfamily also includes IAN-4 protein, which has GTP-binding activity and shares sequence homology with a novel family of putative GTP-binding proteins: the immuno-associated nucleotide (IAN) family. The evolutionary conservation of the IAN family provides a unique example of a plant pathogen response gene conserved in animals. The IAN/IMAP subfamily has been proposed to regulate apoptosis in vertebrates and angiosperm plants, particularly in relation to cancer, diabetes, and infections. The human IAN genes were renamed GIMAP (GTPase of the immunity associated proteins). Pssm-ID: 206651 [Multi-domain] Cd Length: 201 Bit Score: 48.30 E-value: 1.78e-06

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: 48.70 E-value: 1.80e-06

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: 46.77 E-value: 5.37e-06

RsgA GTPase; RsgA (also known as EngC and YjeQ) represents a protein family whose members are broadly conserved in bacteria and are indispensable for growth. The GTPase domain of RsgA is very similar to several P-loop GTPases, but differs in having a circular permutation of the GTPase structure described by a G4-G1-G3 pattern.

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.

EngA1 GTPase contains the first domain of EngA; This EngA1 subfamily CD represents the first 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: 206681 [Multi-domain] Cd Length: 157 Bit Score: 37.03 E-value: 6.58e-03

GTP-binding protein HflX; This protein family is one of a number of homologous small, well-conserved GTP-binding proteins with pleiotropic effects. Bacterial members are designated HflX, following the naming convention in Escherichia coli where HflX is encoded immediately downstream of the RNA chaperone Hfq, and immediately upstream of HflKC, a membrane-associated protease pair with an important housekeeping function. Over large numbers of other bacterial genomes, the pairing with hfq is more significant than with hflK and hlfC. The gene from Homo sapiens in this family has been named PGPL (pseudoautosomal GTP-binding protein-like).
