WebNov 4, 2024 · Here the authors show that oxidation of cysteine residues in the nascent chain can occur within the ribosome exit tunnel, where sufficient space exists for the formation of disulfide bonds. WebIn peptide s and protein s, the sulfur atoms of two cysteine molecules are bonded to each other to make cystine, another amino acid. The bonded sulfur atoms form a disulfide bridge, a principal factor in the shape and function of skeletal and connective tissue proteins and in the great stability of structural proteins such as keratin.
