WebIt is now evident that the half-reactions of acetyl CoA carboxylation are catalyzed by biotin carboxylase and carboxyl transferase. Both components are devoid of biotin and have specific binding sites for free d-biotin, as well as for their respective substrates; hence, the acetyl CoA carboxylation mechanism must involve intersubunit translocation of the … Webdependent formation of biotinyl-5-AMP and pyrophosphate after which the biotinyl group was transferred from the AMP derivative to the appropriate lysyl -amino group of the apotrans-carboxylase. Lane and Lynen also showed that the covalently bound biotinyl prosthetic group, like free biotin, was carboxylated on the 1-N position (5).
