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.

Arsenical pump-driving ATPase ArsA; ArsA ATPase functions as an efflux pump located on the inner membrane of the cell. This ATP-driven oxyanion pump catalyzes the extrusion of arsenite, antimonite and arsenate. Maintenance of a low intracellular concentration of oxyanion produces resistance to the toxic agents. The pump is composed of two subunits, the catalytic ArsA subunit and the membrane subunit ArsB, which are encoded by arsA and arsB genes, respectively. Arsenic efflux in bacteria is catalyzed by either ArsB alone or by ArsAB complex. The ATP-coupled pump, however, is more efficient. ArsA is composed of two homologous halves, A1 and A2, connected by a short linker sequence.

transport-energizing ATPase, TRC40/GET3/ArsA family; Members of this family are ATPases that energize transport, although with different partner proteins for different functions. Recent findings show that TRC40 (GET3 in yeast) in involved in the insertion of tail-anchored membrane proteins in eukaryotes. A similar function is expected for members of this family in archaea. However, the earliest discovery of a function for this protein family is ArsA, an arsenic resistance protein that partners with ArsB (see pfam02040) for As(III) efflux.
