| Cysteine, S-Nitrosylated (SNO-Cys) (BSA) | Nitric oxide (NO), generated by cell type-specific NO- synthase (NOS) isoforms, is a freely diffusible intercellular messenger that functions in target cells in NOS-dependent signaling. S-nitrosylation of cysteine thiols in proteins by the highly labile NO radical has been identified as an important effector of NO-related bioactivity both in NOS- containing cells and intercellular signaling. Most cells contain low levels of nitrosylated proteins that are thought to be regulated by S-nitrosylation and denitrosylation. S-nitrosylation of proteins serves as a ubiquitous post- translational modification that dynamically regulates a broad functional spectrum of proteins. The majority of these proteins are regulated by S-nitrosylation on a single critical cysteine residue within an acidic/basic or hydrophobic structural motif that may also be subject to oxygen- or glutathione-dependent modification.

| Native Cystathionine-β-synthase | Cystathionine-β-synthase, also known as CBS, is an enzyme (EC 4.2.1.22) that in humans is encoded by the CBS gene.

CBS is a multidomain enzyme composed of an N-terminal enzymatic domain and two CBS domains. The CBS gene is the most common locus for mutations associated with homocystinuria. Human cbs performs a crucial step in the biosynthetic pathway of cysteine by providing a regulatory control po...nates methyl groups to a variety of substrates, e.g., neurotransmitters, proteins, and nucleic acids. in mammals, cbs is a highly regulated enzyme, which contains a heme cofactor that functions as a redox sensor, that can modulate its activity in response to changes in the redox potential. if the resting form of cbs in the cell has ferrous heme, the potential exists for activating the enzyme under oxidizing conditions by conversion to the ferric state.
