Accepted name: acetyl-CoA carboxytransferase
Reaction: [biotin carboxyl-carrier protein]-N6-carboxybiotinyl-L-lysine + acetyl-CoA = [biotin carboxyl-carrier protein]-N6-biotinyl-L-lysine + malonyl-CoA
Other name(s): accAD (gene names)
Systematic name: [biotin carboxyl-carrier protein]-N6-carboxybiotinyl-L-lysine:acetyl-CoA:carboxytransferase
Comments: The enzyme catalyses the transfer of a carboxyl group carried on a biotinylated biotin carboxyl carrier protein (BCCP) to acetyl-CoA, forming malonyl-CoA. In some organisms this activity is part of a multi-domain polypeptide that includes the carrier protein and EC, biotin carboxylase (see EC, acetyl-CoA carboxylase). Some enzymes can also carboxylate propanonyl-CoA and butanoyl-CoA (cf. EC, propionyl-CoA carboxylase).
