WebJan 10, 2003 · Acts as a cysteine-protein sulfhydrase by mediating sulfhydration of target proteins: sulfhydration consists of converting -SH groups into -SSH on specific cysteine residues of target proteins such as GAPDH, PTPN1 and NF-kappa-B subunit RELA, thereby regulating their function ( PubMed: 22169477 ). WebLanthionine is an unusual non-protein amino acid, naturally occurring as a byproduct of hydrogen sulfide (H 2 S) biosynthesis from cysteine in vivo [1,2].This reaction is catalyzed by three enzyme systems in humans, cystathionine-β-synthase (CBS) or cystathionase (cystathionine-γ-lyase; CSE), and 3-mercaptopyruvate sulfurtransferase (MST), which …
WebOct 12, 2024 · Hydrogen sulfide (H 2 S) is an identified and recognized gasotransmitter after nitric oxide and carbon oxide.
