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   -!- 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}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_01416}; Peripheral membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_01416}.
CC   -!- MISCELLANEOUS: The ATPase of I.tartaricus is of special interest
CC       because it uses sodium ions instead of protons as the physiological
CC       coupling ion.
CC   -!- SIMILARITY: Belongs to the ATPase delta chain family.
CC       {ECO:0000255|HAMAP-Rule:MF_01416}.
