Cystathionine γ-lyase is a member of the Cys/Met metabolism PLP-dependent enzymes family. Other members include cystathionine γ synthase, cystathionine β lyase, and methionine γ lyase. It is also a member of the broader aspartate aminotransferase family. Like many other PLP-dependent … See more The enzyme cystathionine γ-lyase (EC 4.4.1.1, CTH or CSE; also cystathionase; systematic name L-cystathionine cysteine-lyase (deaminating; 2-oxobutanoate-forming)) breaks down cystathionine into cysteine See more Cysteine is the rate-limiting substrate in the synthetic pathway for glutathione in the eye.

However, transcription is increased by concentrations near 120μM, and inhibited completely at concentrations in excess of 160μM. See more WebOct 12, 2024 · Cystathionine β synthase (CBS), cystathionine γ lyase (CSE), cysteine aminotransferase (CAT), and 3-mercaptopyruvate sulfur transferase (3-MST) are major synthetases of H 2 S. In cardiovascular tissues, CSE and 3-MST are expressed, and CBS to a much lesser extent.
