WebThese data may explain why E. coli employs the more-stable glutathione, rather than cysteine, in millimolar concentrations as its cellular thiol buffer. Similarly, the autoxidation of cysteine residues in proteins is presumably suppressed because the associated amine group is derivatized by a peptide bond, making it unavailable for metal ...
