Cystathionine-β-synthase, also known as CBS, is an enzyme (EC 4.2.1.22) that in humans is encoded by the CBS gene. It catalyzes the first step of the transsulfuration pathway, from homocysteine to cystathionine: L-serine + L-homocysteine $${\displaystyle \rightleftharpoons }$$ L … See more The systematic name of this enzyme class is L-serine hydro-lyase (adding homocysteine; L-cystathionine-forming). Other names in common use include: • β-thionase, • cysteine synthase, See more The human enzyme cystathionine β-synthase is a tetramer and comprises 551 amino acids with a subunit molecular weight of 61 kDa. It displays a modular organization of three modules with the N-terminal heme domain followed by a core that contains the See more Allosteric activation of CBS by adoMet determines the metabolic fate of homocysteine.
