Protein attributes

Sequence length	138 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Produces ATP from ADP in the presence of a proton gradient across the membrane.
Catalytic activity	ATP + H(2)O + H(+)(In) = ADP + phosphate + H(+)(Out).
Subunit structure	F-type ATPases have 2 components, CF(1) - the catalytic core - and CF(0) - the membrane proton channel. CF(1) has five subunits: alpha(3), beta(3), gamma(1), delta(1), epsilon(1). CF(0) has three main subunits: a, b and c.
Subcellular location	Cell membrane; Peripheral membrane proteinBy similarity.
Sequence similarities	Belongs to the ATPase epsilon chain family.
