In enzymology, an acetyl-CoA C-acetyltransferase (EC 2.3.1.9) is an enzyme that catalyzes the chemical reaction

2 acetyl-CoA ${\displaystyle \rightleftharpoons }$ CoA + acetoacetyl-CoA

Hence, this enzyme has one substrate, acetyl-CoA, and two products, CoA and acetoacetyl-CoA.

Acetyl-CoA C-acetyltransferase belongs to the thiolase family of enzymes.

This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. The systematic name of this enzyme class is acetyl-CoA:acetyl-CoA C-acetyltransferase. Other names in common use include acetoacetyl-CoA thiolase, beta-acetoacetyl coenzyme A thiolase, 2-methylacetoacetyl-CoA thiolase [misleading], 3-oxothiolase, acetyl coenzyme A thiolase, acetyl-CoA acetyltransferase, acetyl-CoA:N-acetyltransferase, and thiolase II. This enzyme participates in 10 metabolic pathways: fatty acid metabolism, synthesis and degradation of ketone bodies, valine, leucine and isoleucine degradation, lysine degradation, tryptophan metabolism, pyruvate metabolism, , propanoate metabolism, butanoate metabolism, and .
