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|HAMAP-
CC Rule:MF_00156}.
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 Evidence={ECO:0000256|HAMAP-Rule:MF_00156,
CC ECO:0000256|PIRSR:PIRSR000388-3};
CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000256|HAMAP-Rule:MF_00156,
CC ECO:0000256|PIRSR:PIRSR000388-3};
CC -!- PATHWAY: Cofactor biosynthesis; (R)-pantothenate biosynthesis; (R)-
CC pantoate from 3-methyl-2-oxobutanoate: step 1/2. {ECO:0000256|HAMAP-
CC Rule:MF_00156}.
CC -!- SUBUNIT: Homodecamer; pentamer of dimers.
CC {ECO:0000256|ARBA:ARBA00011424, ECO:0000256|HAMAP-Rule:MF_00156}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00156}.
CC -!- SIMILARITY: Belongs to the PanB family. {ECO:0000256|ARBA:ARBA00008676,
CC ECO:0000256|HAMAP-Rule:MF_00156}.
