Bms1, an essential GTPase, promotes assembly of preribosomal RNA processing complexes; Bms1 is an essential, evolutionarily conserved, nucleolar protein. Its depletion interferes with processing of the 35S pre-rRNA at sites A0, A1, and A2, and the formation of 40S subunits. Bms1, the putative endonuclease Rc11, and the essential U3 small nucleolar RNA form a stable subcomplex that is believed to control an early step in the formation of the 40S subumit. The C-terminal domain of Bms1 contains a GTPase-activating protein (GAP) that functions intramolecularly. It is believed that Rc11 activates Bms1 by acting as a guanine-nucleotide exchange factor (GEF) to promote GDP/GTP exchange, and that activated (GTP-bound) Bms1 delivers Rc11 to the preribosomes.

40S ribosome biogenesis protein Tsr1 and BMS1 C-terminal; RIBIOP_C is a family of eukaryotic proteins from the C-terminus of pre-rRNA-processing protein or ribosome biogenesis proteins BMS1 and TSR1. These proteins act, in the nucleolus, as a molecular switch during maturation of the 40S ribosomal subunit. This domain, domain IV of translation elongation factor selb, adopts the same fold as translation proteins such as domain II of GTP-elongation factor Tu proteins.

GTP translation factor family primarily contains translation initiation, elongation and release factors; The GTP translation factor family consists primarily of translation initiation, elongation, and release factors, which play specific roles in protein translation. In addition, the family includes Snu114p, a component of the U5 small nuclear riboprotein particle which is a component of the spliceosome and is involved in excision of introns, TetM, a tetracycline resistance gene that protects the ribosome from tetracycline binding, and the unusual subfamily CysN/ATPS, which has an unrelated function (ATP sulfurylase) acquired through lateral transfer of the EF1-alpha gene and development of a new function.

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.

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.

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.
