== Function ==
[https://www.uniprot.org/uniprot/ATPA_BOVIN ATPA_BOVIN] Mitochondrial membrane ATP synthase (F(1)F(0) ATP synthase or Complex V) produces ATP from ADP in the presence of a proton gradient across the membrane which is generated by electron transport complexes of the respiratory chain. F-type ATPases consist of two structural domains, F(1) - containing the extramembraneous catalytic core, and F(0) - containing the membrane proton channel, linked together by a central stalk and a peripheral stalk. During catalysis, ATP synthesis in the catalytic domain of F(1) is coupled via a rotary mechanism of the central stalk subunits to proton translocation. Subunits alpha and beta form the catalytic core in F(1). Rotation of the central stalk against the surrounding alpha(3)beta(3) subunits leads to hydrolysis of ATP in three separate catalytic sites on the beta subunits. Subunit alpha does not bear the catalytic high-affinity ATP-binding sites (By similarity).

== Publication Abstract from PubMed ==
The structure of the complex between bovine mitochondrial F(1)-ATPase and a stator subcomplex has been determined at a resolution of 3.2 A. The resolved region of the stator contains residues 122-207 of subunit b; residues 5-25 and 35-57 of F(6); 3 segments of subunit d from residues 30-40, 65-74, and 85-91; and residues 1-146 and 169-189 of the oligomycin sensitivity conferral protein (OSCP). The stator subcomplex represents its membrane distal part, and its structure has been augmented with an earlier structure of a subcomplex containing residues 79-183, 3-123, and 5-70 of subunits b, d, and F(6), respectively, which extends to the surface of the inner membrane of the mitochondrion. The N-terminal domain of the OSCP links the stator with F(1)-ATPase via alpha-helical interactions with the N-terminal region of subunit alpha(E). Its C-terminal domain makes extensive helix-helix interactions with the C- terminal alpha-helix of subunit b from residues 190-207. Subunit b extends as a continuous 160-A long alpha-helix from residue 188 back to residue 79 near to the surface of the inner mitochondrial membrane. This helix appears to be stiffened by other alpha-helices in subunits d and F(6), but the structure can bend inward toward the F(1) domain around residue 146 of subunit b. The linker region between the 2 domains of the OSCP also appears to be flexible, enabling the stator to adjust its shape as it passes over the changing profile of the F(1) domain during a catalytic cycle. The structure of the membrane extrinsic part of bovine ATP synthase is now complete.
