EC 2.3.1.194     
Accepted name: acetoacetyl-CoA synthase
Reaction: acetyl-CoA + malonyl-CoA = acetoacetyl-CoA + CoA + CO2
Other name(s): NphT7
Systematic name: acetyl-CoA:malonyl-CoA C-acetyltransferase (decarboxylating)
Comments: The enzyme from the soil bacterium Streptomyces sp. CL190 produces acetoacetyl-CoA to be used for mevalonate production via the mevalonate pathway. Unlike the homologous EC 2.3.1.180 (β-ketoacyl-[acyl-carrier-protein] synthase III), this enzyme does not accept malonyl-[acyl-carrier-protein] as a substrate.
