WebCystathionine β-synthase (CBS) is a key enzyme in the two-step biosynthesis of cysteine from homocysteine and serine and requires vitamin B 6 for its catalysis ( Fig. 39.1 ). This … 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.
