== Function == | |||
[https://www.uniprot.org/uniprot/ATPA_SPIOL ATPA_SPIOL] Produces ATP from ADP in the presence of a proton gradient across the membrane. The alpha chain is a regulatory subunit. | |||

== Publication Abstract from PubMed == | |||
The chloroplast adenosine triphosphate (ATP) synthase uses the electrochemical proton gradient generated by photosynthesis to produce ATP, the energy currency of all cells. Protons conducted through the membrane-embedded Fo motor drive ATP synthesis in the F1 head by rotary catalysis. We determined the high-resolution structure of the complete cF1Fo complex by cryo-electron microscopy, resolving side chains of all 26 protein subunits, the five nucleotides in the F1 head, and the proton pathway to and from the rotor ring. The flexible peripheral stalk redistributes differences in torsional energy across three unequal steps in the rotation cycle. Plant ATP synthase is autoinhibited by a beta-hairpin redox switch in subunit gamma that blocks rotation in the dark. | |||
