The development of molecular tools for investigating NAD+ metabolism and signalling

Nicotinamide adenine dinucleotide (NAD+) is the substrate used for the introduction of the ubiquitous and highly dynamic PTM in which either one or multiple adenosine diphosphate ribose (ADPr) moieties are covalently attached to a nucleophilic side chain of an specific amino acid in the target protein to regulate cellular pathways including adipogenesis, DNA damage repair and gene expression.

A significant fraction of the nucleophilic amino acid functionalities, most recently histidine and tyrosine, have been identified as ADPr-acceptor sites. In this thesis, new methodologies have been developed to synthesize peptide fragments carrying an ADPr modification to investigate ADP-ribosylation on histidine.
