CC -!- FUNCTION: F(1)F(0) ATP synthase produces ATP from ADP in the presence
CC of a proton or sodium gradient. F-type ATPases consist of two
CC structural domains, F(1) containing the extramembraneous catalytic core
CC and F(0) containing the membrane proton channel, linked together by a
CC central stalk and a peripheral stalk. During catalysis, ATP synthesis
CC in the catalytic domain of F(1) is coupled via a rotary mechanism of
CC the central stalk subunits to proton translocation. {ECO:0000255|HAMAP-
CC Rule:MF_01416}.
CC -!- FUNCTION: This protein is part of the stalk that links CF(0) to CF(1).
CC It either transmits conformational changes from CF(0) to CF(1) or is
CC implicated in proton conduction. {ECO:0000255|HAMAP-Rule:MF_01416}.
CC -!- FUNCTION: In this organism this enzyme may function as an ATP-driven
CC Na(+) ion pump to generate a Na(+) ion electrochemical gradient rather
CC than as an ATP synthase. {ECO:0000269|PubMed:16816177}.
CC -!- SUBUNIT: F-type ATPases have 2 components, F(1) - the catalytic core
CC - and F(0) - the membrane proton channel. F(1) has five subunits:
CC alpha(3), beta(3), gamma(1), delta(1), epsilon(1). F(0) has three main
CC subunits: a(1), b(2) and c(10-14). The alpha and beta chains form an
CC alternating ring which encloses part of the gamma chain. F(1) is
CC attached to F(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.
CC {ECO:0000255|HAMAP-Rule:MF_01416, ECO:0000269|PubMed:16816177}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000255|HAMAP-Rule:MF_01416,
CC ECO:0000269|PubMed:16816177}; Peripheral membrane protein
CC {ECO:0000255|HAMAP-Rule:MF_01416, ECO:0000269|PubMed:16816177}.
CC -!- MISCELLANEOUS: The ATPase of C.paradoxum is of special interest because
CC it uses sodium ions instead of protons as the physiological coupling
CC ion.
CC -!- SIMILARITY: Belongs to the ATPase delta chain family.
