CC -!- FUNCTION: Catalyzes the NADPH-dependent reduction of ketopantoate into
CC pantoic acid. {ECO:0000256|ARBA:ARBA00002919,
CC ECO:0000256|RuleBase:RU362068}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(R)-pantoate + NADP(+) = 2-dehydropantoate + NADPH + H(+);
CC Xref=Rhea:RHEA:16233, ChEBI:CHEBI:11561, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:15980, ChEBI:CHEBI:57783, ChEBI:CHEBI:58349;
CC EC=1.1.1.169; Evidence={ECO:0000256|ARBA:ARBA00048793,
CC ECO:0000256|RuleBase:RU362068};
CC -!- PATHWAY: Cofactor biosynthesis; (R)-pantothenate biosynthesis; (R)-
CC pantoate from 3-methyl-2-oxobutanoate: step 2/2.
CC {ECO:0000256|ARBA:ARBA00004994, ECO:0000256|RuleBase:RU362068}.
CC -!- SIMILARITY: Belongs to the ketopantoate reductase family.
CC {ECO:0000256|ARBA:ARBA00007870, ECO:0000256|RuleBase:RU362068}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:RIH65330.1}.
