Function

[ATP5J_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. Also involved in the restoration of oligomycin-sensitive ATPase activity to depleted F1-F0 complexes.

Publication Abstract from PubMed

The ATP synthase enzyme structure includes two stalk assemblies, the central stalk and the peripheral stalk. Catalysis involves rotation of the central stalk assembly together with the membrane-embedded ring of c-subunits driven by the trans-membrane proton-motive force, while the alpha and beta-subunits of F(1) are prevented from co-rotating by their attachment to the peripheral stalk. In the absence of structures of either the intact peripheral stalk or larger complexes containing it, we are studying its individual components and their interactions to build up an overall picture of its structure. Here, we describe an NMR structural characterisation of F(6), which is a 76-residue protein located in the peripheral stalk of the bovine ATP synthase and is essential for coupling between the proton-motive force and catalysis. Isolated F(6) has a highly flexible structure comprising two helices packed together through a loose hydrophobic core and connected by an unstructured linker. Analysis of chemical shifts, (15)N relaxation and RDC measurements confirm that the F(6) structure is flexible on a wide range of timescales ranging from nanoseconds to seconds. The relationship between this structure for isolated F(6) and its role in the intact peripheral stalk is discussed.
