Cooper et al suggest that reactive oxygen species act as nanotransducers in cell signalling and that… Show more Cooper et al suggest that reactive oxygen species act as nanotransducers in cell signalling and that their primary targets are specific cysteine residues in key protein molecules. They also suggest that the diversity of oxidative modifications which may occur to cysteine residues may allow an individual target protein to display a graded response to diverse effectors (signals). (a)Describe the diversity of cysteine thiol modifications that may occur, indicate those that are reversible and provide some examples of regulatory functions through these modifications. (b) Compare and contrast this form of regulatory posttranslational modification with the regulatory posttranslational modifications achieved by protein phosphorylation/dephosphorylation • Show less
