CC -!- FUNCTION: Catalyzes the reversible reaction in which hydroxymethyl
CC group from 5,10-methylenetetrahydrofolate is transferred onto alpha-
CC ketoisovalerate to form ketopantoate. {ECO:0000256|RuleBase:RU362100}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(6R)-5,10-methylene-5,6,7,8-tetrahydrofolate + 3-methyl-2-
CC oxobutanoate + H2O = (6S)-5,6,7,8-tetrahydrofolate + 2-
CC dehydropantoate; Xref=Rhea:RHEA:11824, ChEBI:CHEBI:11561,
CC ChEBI:CHEBI:11851, ChEBI:CHEBI:15377, ChEBI:CHEBI:15636,
CC ChEBI:CHEBI:57453; EC=2.1.2.11;
CC Evidence={ECO:0000256|ARBA:ARBA00000344,
CC ECO:0000256|RuleBase:RU362100};
CC -!- PATHWAY: Cofactor biosynthesis; (R)-pantothenate biosynthesis; (R)-
CC pantoate from 3-methyl-2-oxobutanoate: step 1/2.
CC {ECO:0000256|ARBA:ARBA00005033, ECO:0000256|RuleBase:RU362100}.
CC -!- SIMILARITY: Belongs to the PanB family. {ECO:0000256|ARBA:ARBA00008676,
CC ECO:0000256|RuleBase:RU362100}.
