Cystein peptidase
WebCysteine (symbol Cys or C; [3] / ˈsɪstɪiːn /) [4] is a semiessential [5] proteinogenic amino acid with the formula HOOC−CH (−NH2)−CH2−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. WebJan 1, 2002 · Abstract. XCP1 is a xylem-specific papain-like cysteine peptidase in Arabidopsis. To determine whether XCP1 could be involved in tracheary element autolysis, promoter activity and localization of XCP1 were investigated using XCP1 promoter-β-glucuronidase fusions and immunofluorescence confocal microscopy. A tracheary …
