Structural highlights 2jmx is a 2 chain structure with sequence from Bos taurus. Full experimental information is available from OCA. For a guided tour on the structure components use FirstGlance. Method: Solution NMR Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function ATPO_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. Part of the complex F(0) domain and the peripheric stalk, which acts as a stator to hold the catalytic alpha(3)beta(3) subcomplex and subunit a/ATP6 static relative to the rotary elements. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMed The peripheral stalk of ATP synthase acts as a stator holding the alpha(3)beta(3) catalytic subcomplex and the membrane subunit a against the torque of the rotating central stalk and attached c ring. In bovine mitochondria, the N-terminal domain of the oligomycin sensitivity conferral protein (OSCP-NT; residues 1-120) anchors one end of the peripheral stalk to the N-terminal tails of one or more alpha subunits of the F(1) subcomplex. Here, we present an NMR characterisation of the interaction between OSCP-NT and a peptide corresponding to residues 1-25 of the alpha-subunit of bovine F(1)-ATPase. The interaction site contains adjoining hydrophobic surfaces of helices 1 and 5 of OSCP-NT binding to hydrophobic side-chains of the alpha-peptide.
