In enzymology, a biotin—[methylmalonyl-CoA-carboxytransferase] ligase (EC 6.3.4.9) is an enzyme that catalyzes the chemical reaction
- ATP + biotin + apo-[methylmalonyl-CoA:pyruvate carboxytransferase] AMP + diphosphate + [methylmalonyl-CoA:pyruvate carboxytransferase]
The 3 substrates of this enzyme are ATP, biotin, and [[apo-[methylmalonyl-CoA:pyruvate carboxytransferase]]], whereas its 3 products are AMP, diphosphate, and methylmalonyl-CoA:pyruvate carboxytransferase.
This enzyme belongs to the family of ligases, specifically those forming generic carbon-nitrogen bonds. The systematic name of this enzyme class is biotin:apo[methylmalonyl-CoA:pyruvate carboxytransferase] ligase (AMP-forming). This enzyme participates in biotin metabolism.
