WebHomocystinuria is caused by problems with the enzyme “cystathionine beta-synthase” (CBS). In people with homocystinuria, CBS is either missing or not working properly. This enzyme’s job is to break down methionine. When the CBS enzyme is not working correctly, methionine and another amino acid, homocystine, build up in the blood and cause … 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.
