In enzymology, a cysteine synthase (EC 2.5.1.47) is an enzyme that catalyzes the chemical reaction O -acetyl-L-serine + hydrogen sulfide L-cysteine + acetate Thus, the two substrates of this enzyme are O -acetyl-L-serine and hydrogen sulfide, whereas its two products are L-cysteine and acetate. This enzyme belongs to the family of transferases, specifically those transferring aryl or alkyl gro… WebCysteine synthase follows a ping-pong enzymatic reaction mechanism, typical of PLP-dependent enzymes (Figure 1) [14,15]. In the resting state, the PLP cofactor forms an internal Schiff base with a catalytic lysine residue. WebNov 28, 2024 · Hydrogen sulfide (H2S) and its bioderivatives analogs, such as L-cysteine (L-Cys) and glutathione (GSH), are ubiquitous biological thiols in the physiological and pathological processes of living systems.
