Cysteine oxidation and disulfide formation in the ribosomal exit tunnel

As protein synthesis takes place, newly synthesized polypeptide chain passes through the ribosomal exit tunnel, which can accommodate up to 70 residues in the case of a helical peptide. Here the authors show that oxidation of cysteine residues in the nascent chain can occur within the ribosome exit...

Description
Summary:As protein synthesis takes place, newly synthesized polypeptide chain passes through the ribosomal exit tunnel, which can accommodate up to 70 residues in the case of a helical peptide. 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.
