Crystal Structure of the A3B3 complex from V-ATPase

Structural highlights

3gqb is a 4 chain structure with sequence from Thet8. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Gene:	atpA, TTHA1273 (THET8), atpB, TTHA1272 (THET8)
Activity:	H(+)-transporting two-sector ATPase, with EC number 3.6.3.14
Resources:	FirstGlance, OCA, PDBe, RCSB, PDBsum

Function

[VATA_THET8] Produces ATP from ADP in the presence of a proton gradient across the membrane. The V-type alpha chain is a catalytic subunit. [VATB_THET8] Produces ATP from ADP in the presence of a proton gradient across the membrane. The V-type beta chain is a regulatory subunit.

Publication Abstract from PubMed

Vacuolar-type ATPases (V-ATPases) exist in various cellular membranes of many organisms to regulate physiological processes by controlling the acidic environment. Here, we have determined the crystal structure of the A(3)B(3) subcomplex of V-ATPase at 2.8 A resolution. The overall construction of the A(3)B(3) subcomplex is significantly different from that of the alpha(3)beta(3) sub-domain in F(o)F(1)-ATP synthase, because of the presence of a protruding 'bulge' domain feature in the catalytic A subunits. The A(3)B(3) subcomplex structure provides the first molecular insight at the catalytic and non-catalytic interfaces, which was not possible in the structures of the separate subunits alone. Specifically, in the non-catalytic interface, the B subunit seems to be incapable of binding ATP, which is a marked difference from the situation indicated by the structure of the F(o)F(1)-ATP synthase. In the catalytic interface, our mutational analysis, on the basis of the A(3)B(3) structure, has highlighted the presence of a cluster composed of key hydrophobic residues, which are essential for ATP hydrolysis by V-ATPases.
