Cystathionine beta-synthase-like protein

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… WebCystathionine beta-synthase (CBS) converts HCY to GSH via the transsulfuration pathway with vitamin B6 as cofactor [53–55] ( Fig. 3.2). The tripeptide GSH is the main antioxidant and detoxification molecule. Keeping the balance between methylation and transsulfuration depends on methionine levels and allosteric activation of CBS by SAM.
