Allosteric activation of CBS by adoMet determines the metabolic fate of homocysteine. Mammalian CBS is activated 2.5-5-fold by AdoMet with a dissociation constant of 15 μM. AdoMet is an allosteric activator that increases the Vmax of the CBS reaction but does not affect the Km for the substrates. In other words, AdoMet stimulates CBS activity by increasing the turnover rate rather than the binding of substrates to the enzyme. This protein may use the morpheein model of allosteric regu… WebJan 10, 2024 · LOC102724560 (Cystathionine Beta-Synthase Like) is a Protein Coding gene.
