WebSummary. Enables cystathionine beta-lyase activity and cysteine-S-conjugate beta-lyase activity. Involved in methionine biosynthetic process and transsulfuration. Located in … 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.
