Cystathionine gamma synthase
WebDec 9, 2024 · Many enzymes require pyridoxal 5’-phosphate (PLP) as an essential cofactor and share active site residues in mediating diverse enzymatic reactions. Methionine can be converted into cysteine by cystathionine γ-lyases (CGLs) through a transsulfuration reaction dependent on PLP. In bacteria, MccB, also known as YhrB, … WebSep 29, 2024 · The endogenous production of H 2 S is catalyzed by 3 enzymes: cystathionine β‐synthase, cystathionine γ‐lyase (CSE), and 3‐mercaptopyruvate sulfurtransferase. 5 While, all 3 enzymes have been found in the cardiovascular system, CSE is believed to be expressed primarily in the heart and vasculature and responsible …
