Chemical reporters for exploring ADP-ribosylation and AMPylation at the host-pathogen interface.

Chemical reporters for exploring ADP-ribosylation and AMPylation at the host-pathogen interface. Curr Opin Chem Biol. 2014 Oct 27;23C:56-62 Authors: Westcott NP, Hang HC Abstract Bacterial pathogens secrete protein toxins and effectors that hijack metabolites to covalently modify host proteins and interfere with their function during infection. Adenosine metabolites, such as nicotinamide adenine dinucleotide (NAD) and adenosine triphosphate (ATP), have in particular been co-opted by these secreted virulence factors to reprogram host pathways. While some host targets for secreted virulence factors have been identified, other toxin and effector substrates have been elusive, which require new methods for their characterization. In this review, we focus on chemical reporters based on NAD and ATP that should facilitate the discovery and characterization of adenosine diphosphate (ADP)-ribosylation and adenylylation/AMPylation in bacterial pathogenesis and cell biology.
