BKACE, beta-keto acid cleavage enzyme plays, a role in lysine degradation. In certain instances it catalyses the conversion of 3-keto-5-aminohexanoate and acetyl-CoA into acetoacetate and 3-aminobutyryl-CoA [1]. The family is found to have at least 14 slightly different potential new enzymatic activities, all of which can therefore be designated as beta-keto acid cleavage enzymes [2].	Domain
