Taxonomic lineage

Eukaryota › Metazoa › Chordata › Craniata › Vertebrata › Euteleostomi › Mammalia › Eutheria › Euarchontoglires › Primates › Haplorrhini › Catarrhini › Hominidae › Homo

Protein attributes

Sequence length	520 AA.
Sequence status	Complete.
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.
Sequence caution	The sequence AAH00297.2 differs from that shown. Reason: Erroneous initiation.
