method to controlpeptide folding, particularly when α‐helical secondarystructure is the target. Here, we examine the application of oxime bridges, formed by the chemoselective reaction between aminooxy and aldehyde side chains, for the stabilization of a helical peptide involved in a protein–protein complex. A series of sequence variants of the dimeric coiled coil GCN4‐p1 bearing oxime bridges at

Efficient strategies for the introduction of arginine residues featuring acetylene or azide moieties in their side chains are described. The substituents are introduced in a way that maintains the basicity of the guanidine moiety. The methodology can be used e.g. for non-invasive labeling of arginine-containing peptides. Its applicability is demonstrated by the introduction of ‘click’ handles into a Protein Kinase C (PKC) pseudosubstrate peptide, and the subsequent preparation and evaluation of a novel bisubstrate-based inhibitor based on such a peptide.

Metalloproteins are of utmost importance for nearly all biological processes. Valuable information about their functionalities came from mutagenesis studies and led to the denovodesign of artificial proteins. Advances in peptide chemistry enable the total synthesis of complete proteins and allow the incorporation of non-proteinogenic aminoacids. Chelating aminoacids utilized to introduce artificial
