Synthetic mono-ADPr-peptides are useful for structural, biochemical, and proteomics studies. We describe here a protocol for the preparation of mono-ADPr-peptides based on a fairly standard Fmoc-based solid-phase synthesis. Phosphoribosylated precursor building blocks are introduced into the peptide chain on solid-phase and subsequently converted to ADPr-sites by chemical phosphorylation with adenosine phosphoramidite. Suitably protected phosphoribosylated glutamine, asparagine, and citrulline building blocks described in this protocol allow introduction of ADP-Gln, ADPr-Asn, and ADPr-Cit into peptide chains as demonstrated for three peptides. Trifunctional amino acids, for which base-sensitive side-chain protection is available, can be accommodated in the sequences flanking the ADPr-cites.
