Protein attributes

Sequence length	138 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Produces ATP from ADP in the presence of a proton gradient across the membrane. HAMAP MF_00530
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: a, b and c.
Subcellular location	Cell membrane; Peripheral membrane protein By similarity HAMAP MF_00530.
Sequence similarities	Belongs to the ATPase epsilon chain family.
