Chains	Enzyme Name	Description	Catalytic Residues
A	acetyl-CoA C-acyltransferase M-CSA #77	Thiolases form a ubiquitous family of enzymes found in both prokaryotes and eukaryotes. Thiolases catalyse the reversible two step cleavage of acyl-CoA into CoA and acetyl-CoA. There are two classes of thiolases, I and II. This entry represents the Class II thiolases. Class II only acts upon acetoacetyl-CoA and its main function is to synthesise this compound in a Claisen condensation reaction important in several biosynthetic pathways.
