General annotation (Comments)

Function	Key component of the proton channel; it plays a direct role in the translocation of protons across the membrane By similarity. HAMAP MF_01393
Subunit structure	F-type ATPases have 2 components, CF1 - the catalytic core - and CF0 - the membrane proton channel. CF1 has five subunits: alpha3, beta3, gamma1, delta1, epsilon1. CF0 has four main subunits: a, b, b' and c By similarity. HAMAP MF_01393
Subcellular location	Plastid › chloroplast thylakoid membrane; Multi-pass membrane protein By similarity HAMAP MF_01393.
Sequence similarities	Belongs to the ATPase A chain family.
