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:0000250}.
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 -!- SUBUNIT: Heterodimer of an alpha and a beta chain. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000250}; Multi-pass
CC membrane protein {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the PNT beta subunit family. {ECO:0000305}.
