CC -!- FUNCTION: Hydrolyzes 3-hydroxyisobutyryl-CoA (HIBYL-CoA), a saline
CC catabolite. Has high activity toward isobutyryl-CoA. Could be an
CC isobutyryl-CoA dehydrogenase that functions in valine catabolism.
CC {ECO:0000256|RuleBase:RU369070}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=3-hydroxy-2-methylpropanoyl-CoA + H2O = 3-hydroxy-2-
CC methylpropanoate + CoA + H(+); Xref=Rhea:RHEA:20888,
CC ChEBI:CHEBI:11805, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:57287, ChEBI:CHEBI:57340; EC=3.1.2.4;
CC Evidence={ECO:0000256|RuleBase:RU369070};
CC -!- PATHWAY: Amino-acid degradation; L-valine degradation.
CC {ECO:0000256|RuleBase:RU369070}.
CC -!- SIMILARITY: Belongs to the enoyl-CoA hydratase/isomerase family.
CC {ECO:0000256|RuleBase:RU369070}.
