CC Evidence={ECO:0000256|HAMAP-Rule:MF_00563,
CC ECO:0000256|RuleBase:RU000548};
CC -!- COFACTOR:
CC Name=NAD(+); Xref=ChEBI:CHEBI:57540;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00563,
CC ECO:0000256|PIRSR:PIRSR001109-2, ECO:0000256|RuleBase:RU000548};
CC Note=Binds 1 NAD(+) per subunit. {ECO:0000256|HAMAP-Rule:MF_00563,
CC ECO:0000256|PIRSR:PIRSR001109-2, ECO:0000256|RuleBase:RU000548};
