Protein existence	Evidence at protein level.

General annotation (Comments)

Function	This enzyme condenses acetyl-CoA with acetoacetyl-CoA to form HMG-CoA, which is the substrate for HMG-CoA reductase.
Catalytic activity	Acetyl-CoA + H2O + acetoacetyl-CoA = (S)-3-hydroxy-3-methylglutaryl-CoA + CoA.
Pathway	Metabolic intermediate biosynthesis; (R)-mevalonate biosynthesis; (R)-mevalonate from acetyl-CoA: step 2/3.
Subcellular location	Cytoplasm.
Sequence similarities	Belongs to the HMG-CoA synthase family.
