Produces ATP from ADP in the presence of a proton gradient across the membrane; the alpha chain is a catalytic subunit

F0F1 ATP synthase subunit alpha is part of the catalytic core of the F-ATPase that uses a proton gradient to drive ATP synthesis; it hydrolyzes ATP to build the proton gradient and is found in bacterial, mitochondrial, and chloroplast membranes

The sequences of ATP synthase F1 alpha and beta subunits are related and both contain a nucleotide-binding site for ATP and ADP. They have a common amino terminal domain but vary at the C-terminus. The beta chain has catalytic activity, while the alpha chain is a regulatory subunit. The alpha-subunit contains a highly conserved adenine-specific noncatalytic nucleotide-binding domain. The conserved amino acid sequence is Gly-X-X-X-X-Gly-Lys. Proton translocating ATP synthase F1, alpha subunit is homologous to proton translocating ATP synthase archaeal/vacuolar(V1), B subunit.
