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. WebEnables cystathionine beta-lyase activity and cysteine-S-conjugate beta-lyase activity. Involved in methionine biosynthetic process and transsulfuration. Located in peroxisome.
