摘要: ADP-ribosylation is a post-translational modification of proteins that has required the development specific technical approaches for full definition its physiological roles and regulation. The identification enzymes substrates this reaction an instrumental step toward these aims. Here we describe method separation ADP-ribosylated based on use ADP-ribose-binding macro domain thermophilic protein Af1521, coupled to mass spectrometry analysis identification. This foresees coupling resin, affinity-based pull-down assay, specificity resulting from clearing cell lysates with mutated unable bind ADP-ribose. By both mono- poly-ADP-ribosylated have been identified.
