WebProtein modification reagents are chemical agents used to modify amino acid side chains to alter the native charges, block or expose reactive binding sites, inactivate functional groups, or change functional groups to create targets for crosslinking and labeling. Various reagents are available to meet your protein modification strategy. WebCysteine (symbol Cys or C; / ˈ s ɪ s t ɪ iː n /) is a semiessential proteinogenic amino acid with the formula HOOC−CH(−NH 2)−CH 2 −SH.The thiol side chain in cysteine often participates in enzymatic reactions as a nucleophile.Cysteine is chiral, only L-cysteine is found in nature.. The thiol is susceptible to oxidation to give the disulfide derivative …
