CF(1) has five subunits: CC alpha(3), beta(3), gamma(1), delta(1), epsilon(1). CF(0) has four main CC subunits: a, b, b' and c. else CC -!- SUBUNIT: F-type ATPases have 2 components, CF(1) - the catalytic core CC - and CF(0) - the membrane proton channel. CF(1) has five subunits: CC alpha(3), beta(3), gamma(1), delta(1), epsilon(1). CF(0) has three main CC subunits: a(1), b(2) and c(9-12). The alpha and beta chains form an CC alternating ring which encloses part of the gamma chain. CF(1) is CC attached to CF(0) by a central stalk formed by the gamma and epsilon CC chains, while a peripheral stalk is formed by the delta and b chains. end case case CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane; Multi- CC pass membrane protein. else case and not CC -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane; Multi-pass membrane CC protein. else case CC -!- SUBCELLULAR LOCATION: Cell inner membrane; Multi-pass membrane protein. else case not defined or CC -!- SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein. else case CC -!- SUBCELLULAR LOCATION: Cell inner membrane; Multi-pass membrane protein. end case CC -!- SIMILARITY: Belongs to the ATPase A chain family.
