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 is the only pathway in humans that leads to cysteine production. This pathway competes for homocysteine with homocysteine remethylation by MS in the methyl cycle pathway. WebSep 9, 2024 · As mentioned above, cystathionine-β-synthase is an enzyme involved in the transsulfuration pathway, which is how the body regulates its levels of sulfur …
