Protein attributes

Sequence length	242 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

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-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 three main subunits: a1, b2 and c(9-12). The alpha and beta chains form an alternating ring which encloses part of the gamma chain. CF1 is attached to CF0 by a central stalk formed by the gamma and epsilon chains, while a peripheral stalk is formed by the delta and b chains By similarity.
Subcellular location	Cell inner membrane; Multi-pass membrane protein By similarity HAMAP-Rule MF_01393.
Sequence similarities	Belongs to the ATPase A chain family.
