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. WebMar 23, 2024 · Cystathionine β -synthase (CBS) regulates homocysteine metabolism and contributes to hydrogen sulfide (H 2 S) biosynthesis through which it plays multifunctional roles in the regulation of cellular energetics, redox status, DNA methylation, and protein modification. Inactivating mutations in CBS contribute to the pathogenesis of the …
