UniProt Comments
Function: Key component of the proton channel; it plays a direct role in the translocation of protons across the membrane. HAMAP-Rule 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.
Subcellular location: Plastid › chloroplast thylakoid membrane; Multi-pass membrane protein HAMAP-Rule MF_01393.
Sequence similarities: Belongs to the ATPase A chain family.
Caution: This has been proposed to be processed from a precursor (Ref.4); however no signal is predicted by signal sequence detection programs.
