For the first two, biotin serves as a cofactor responsible for transfer of bicarbonate to acetyl-CoA, converting it to malonyl-CoA for fatty acid synthesis. PC participates in gluconeogenesis. MCC catalyzes a step in leucine metabolism. PCC catalyzes a step in the metabolism of propionyl-CoA. Metabolic degradation of the biotinylated carboxylases leads to the formation of biocytin. This compound is further degraded by biotinidase to release biotin, which is then reutilized by holocarboxylase synthetase.
