Web7.10.3.2.3 Cystathionine β-synthase. CBS catalyzes a β-replacement reaction condensing homocysteine and serine to form cystathionine. This reaction is the committed step in the synthesis of cysteine from methionine by transsulfuration. CBS is the most common locus for mutations associated with homocystinuria, an inherited metabolic disorder.
