CC -!- FUNCTION: The transhydrogenation between NADH and NADP is coupled to
CC respiration and ATP hydrolysis and functions as a proton pump across
CC the membrane. {ECO:0000256|ARBA:ARBA00003943,
CC ECO:0000256|PIRNR:PIRNR000203}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H(+)(in) + NAD(+) + NADPH = H(+)(out) + NADH + NADP(+);
CC Xref=Rhea:RHEA:47992, ChEBI:CHEBI:15378, ChEBI:CHEBI:57540,
CC ChEBI:CHEBI:57783, ChEBI:CHEBI:57945, ChEBI:CHEBI:58349; EC=7.1.1.1;
CC Evidence={ECO:0000256|ARBA:ARBA00000006,
CC ECO:0000256|PIRNR:PIRNR000203};
CC -!- SUBCELLULAR LOCATION: Cell inner membrane
CC {ECO:0000256|ARBA:ARBA00004429}; Multi-pass membrane protein
CC {ECO:0000256|ARBA:ARBA00004429}. Membrane
CC {ECO:0000256|ARBA:ARBA00004141}; Multi-pass membrane protein
