Functional Family Acetyl-coenzyme A carboxylase carboxyl transferase subunit alpha

Enzyme Information

2.1.3.15
Acetyl-CoA carboxytransferase.
based on mapping to UniProt P0ABD5
[Biotin carboxyl-carrier protein]-N(6)-carboxybiotinyl-L-lysine + acetyl- CoA = [biotin carboxyl-carrier protein]-N(6)-biotinyl-L-lysine + malonyl- CoA.
-!- The enzyme catalyzes 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 6.3.4.14 (see EC 6.4.1.2). -!- Some enzymes can also carboxylate propanonyl-CoA and butanoyl-CoA (Cf. EC 6.4.1.3).
