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 … A prosthetic group is the non-amino acid component that is part of the structure of the heteroproteins or conjugated proteins, being tightly linked to the apoprotein. Not to be confused with the cosubstrate that binds to the enzyme apoenzyme (either a holoprotein or heteroprotein) by non-covalent binding a non-protein (non-amino acid) This is a component of a conjugated protein that is required for the protein's biological activity.
