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(+);
