During searching, the taxonomy of the source organism was restricted to Gallus gallus, and to the possible modifications of polypeptide chains to methionine oxidation.
Recently, this has become especially true for the modification of polypeptides (monomers or polymers), which has resulted in a plethora of novel polymers and materials.
With this in mind, this highlight focuses on the recent literature concerning the modification of polypeptides by the use of thiol-X chemistry, in particular to synthetic polypeptides either at the monomer or polymer stage modified by thiol-ene, -Michael addition, and -yne chemistries.
Kinnunen and colleagues reported that modification of polypeptides by Poxno-PC improved protein binding to artificial membranes [31].
It has been suggested that NO could inhibit the transcription/translation of adhesion molecules through either scavenging of signal oxidants produced in response to cytokines, or through covalent modification of polypeptides in the signaling pathway, like IkB.
It has been suggested that NO might limit the transcription/translation of adhesion molecules either by scavenging signal oxidants (produced in response to cytokines) or by covalent modification of polypeptides in the signaling pathway, like the inhibitor of kappaB (IkB).
Co- and post-translational modifications of the polypeptide chain and the cofactor are also possible and can be assessed only with the native material.
PEGylation of these polypeptides does not alter the self-association or conformational behavior of the polypeptide, suggesting potential applications in the development of assembled delivery vehicles, as modification of the polypeptides should be a useful strategy for controlling assembly.
This is achieved through posttranslational modifications of the p53 polypeptide, while there is no marked induction of p53 mRNA levels after DNA damage or other stress.
Post-polymerization modifications of the alkene moiety of polypeptide are achieved with a high efficiency through a typical radical thiol-ene addition using a range of thiol-containing compounds, indicating the broad scope of this method as a conjugation tool for functional molecules.
