WebTable 1 reveals that, with the possible exception of cystathionine γ-lyase, no mammalian cysteine S-conjugate β-lyase identified thus far catalyzes a β-lyase reaction as its ‘natural’ physiological reaction. Although cystathionine γ-lyase normally catalyzes a γ-elimination reaction, it can also catalyze β-elimination reactions that ... WebNov 2, 2024 · Cystathionine γ-lyase (CGL) is a PLP-dependent enzyme that catalyzes the last step of the reverse transsulfuration route for endogenous cysteine biosynthesis. The canonical CGL-catalyzed process consists of an α,γ-elimination reaction that breaks down cystathionine into cysteine, α-ketobutyrate, and ammonia. ...
