CC -!- FUNCTION: Catalyzes the condensation of acetyl-CoA with acetoacetyl-CoA
CC to form HMG-CoA. {ECO:0000256|RuleBase:RU364071}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=acetoacetyl-CoA + acetyl-CoA + H2O = (3S)-hydroxy-3-
CC methylglutaryl-CoA + CoA + H(+); Xref=Rhea:RHEA:10188,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:43074,
CC ChEBI:CHEBI:57286, ChEBI:CHEBI:57287, ChEBI:CHEBI:57288; EC=2.3.3.10;
CC Evidence={ECO:0000256|RuleBase:RU364071};
CC -!- PATHWAY: Metabolic intermediate biosynthesis; (R)-mevalonate
CC biosynthesis; (R)-mevalonate from acetyl-CoA: step 2/3.
CC {ECO:0000256|RuleBase:RU364071}.
CC -!- SIMILARITY: Belongs to the thiolase-like superfamily. HMG-CoA synthase
CC family. {ECO:0000256|ARBA:ARBA00007061, ECO:0000256|RuleBase:RU364071}.
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:RLN36370.1}.
