Did you know?
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 L-cystathionine + H2O CBS uses the cofactor pyridoxal-phosphate (PLP) and can be allosterically regul… WebDec 9, 2024 · Cystathionine is then cleaved at the β position from the cysteine by cystathionine β-lyase MetC, producing homocysteine, the precursor of methionine . In the biosynthesis of cysteine, cystathionine β-synthase , called MccA or CysM in bacteria, mediates the C-S linkage of homocysteine and serine to produce cystathionine as the …
WebCystathionine beta-synthase (CBS) is a unique heme- containing enzyme that catalyzes a pyridoxal 5'-phosphate (PLP)-dependent condensation of serine and homocysteine to give cystathionine. WebCystathionine beta-synthase (CBS) is a key regulator of homocysteine metabolism. Although eukaryotic CBS have a similar domain architecture with a catalytic core and a C-terminal Bateman module, their regulation varies widely across phyla. In human CBS (HsCBS), the C-terminus has an autoinhibitory effect by acting as a cap that avoids the …
