Protein Classification

P-loop NTPase family protein( domain architecture ID 1562424)

P-loop NTPase (nucleoside triphosphate hydrolase) family protein contains two conserved sequence signatures, the Walker A motif (the P-loop proper) and Walker B motif which bind, respectively, the beta and gamma phosphate moieties of the bound nucleotide (typically ATP or GTP), and a Mg(2+) cation

P-loop containing Nucleoside Triphosphate Hydrolases; Members of the P-loop NTPase domain superfamily are characterized by a conserved nucleotide phosphate-binding motif, also referred to as the Walker A motif (GxxxxGK[S/T], where x is any residue), and the Walker B motif (hhhh[D/E], where h is a hydrophobic residue). The Walker A and B motifs bind the beta-gamma phosphate moiety of the bound nucleotide (typically ATP or GTP) and the Mg2+ cation, respectively. The P-loop NTPases are involved in diverse cellular functions, and they can be divided into two major structural classes: the KG (kinase-GTPase) class which includes Ras-like GTPases and its circularly permutated YlqF-like; and the ASCE (additional strand catalytic E) class which includes ATPase Binding Cassette (ABC), DExD/H-like helicases, 4Fe-4S iron sulfur cluster binding proteins of NifH family, RecA-like F1-ATPases, and ATPases Associated with a wide variety of Activities (AAA). Also included are a diverse set of nucleotide/nucleoside kinase families.

 32-164 4.38e-67

CDC/Septin GTPase family; Septins are a conserved family of GTP-binding proteins associated with diverse processes in dividing and non-dividing cells. They were first discovered in the budding yeast S. cerevisiae as a set of genes (CDC3, CDC10, CDC11 and CDC12) required for normal bud morphology. Septins are also present in metazoan cells, where they are required for cytokinesis in some systems, and implicated in a variety of other processes involving organization of the cell cortex and exocytosis. In humans, 12 septin genes generate dozens of polypeptides, many of which comprise heterooligomeric complexes. Since septin mutants are commonly defective in cytokinesis and formation of the neck formation of the neck filaments/septin rings, septins have been considered to be the primary constituents of the neck filaments. Septins belong to the GTPase superfamily for their conserved GTPase motifs and enzymatic activities.

 32-162 2.55e-50

Septin; Members of this family include CDC3, CDC10, CDC11 and CDC12/Septin. Members of this family bind GTP. As regards the septins, these are polypeptides of 30-65kDa with three characteriztic GTPase motifs (G-1, G-3 and G-4) that are similar to those of the Ras family. The G-4 motif is strictly conserved with a unique septin consensus of AKAD. Most septins are thought to have at least one coiled-coil region, which in some cases is necessary for intermolecular interactions that allow septins to polymerize to form rod-shaped complexes. In turn, these are arranged into tandem arrays to form filaments. They are multifunctional proteins, with roles in cytokinesis, sporulation, germ cell development, exocytosis and apoptosis.
