WebSep 16, 2013 · Cystathionine β-synthase (CBS; E.C. 4.2.1.22) is a pyridoxal-5′-phosphate (PLP)–dependent enzyme that plays a pivotal role in sulfur amino acid metabolism. CBS catalyzes a β-replacement reaction in which the hydroxyl group of l -serine (Ser) is replaced by l -homocysteine (Hcy), yielding cystathionine (Cth) ( 1 ). WebApr 10, 2024 · Cystathionine-β-synthase (CBS) is highly expressed in the liver, and deficiencies in Cbs lead to hyperhomocysteinemia (HHCy) and disturbed production of antioxidants such as hydrogen sulfide.
