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 … WebFeb 1, 2007 · The cysteine (or serine) at the N-terminus of the intein, when mutated to alanine, eliminates N-terminal cleavage activity, and therefore also inhibits splicing (Fig. 1, right). With this mutation, C-terminal cleavage is isolated, and the peptide bond between the C-terminal of the intein (asparagine) and the N-terminal of the C-extein is cleaved.
