WebJun 11, 2024 · We identified cystathionine γ-lyase (CSE) as the primary generator of H 2 S in two major human pathogens, Staphylococcus aureus and Pseudomonas aeruginosa, and discovered small molecules that inhibit bacterial CSE. These inhibitors potentiate bactericidal antibiotics against both pathogens in vitro and in mouse models of infection. 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.
