Did you know?
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. WebCystathionine-β-synthase (CBS) is upregulated and hydrogen sulfide (H 2 S) production is increased in various types of cancer including colon, ovarian, breast and lung cancer [7–12]. The functional consequence of increased cellular H 2 S production is stimulation of cellular bioenergetics, tumor growth and proliferation (reviewed in [ 13 ]).
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).
