|Abstract||Despite recent mass spectrometry MS-based breakthroughs comprehensive ADP-ribose ADPr-acceptor amino acid identification and ADPr-site localization remain challenging. Here we report the establishment of an unbiased multistep ADP-ribosylome data analysis workflow that led to the identification of tyrosine as a novel ARTD1PARP1-dependent in vivo ADPr-acceptor amino acid. MS analyses of in vitro ADP-ribosylated proteins confirmed tyrosine as an ADPr-acceptor amino acid in RPS3A Y155 and HPF1 Y238 and demonstrated that trans-modification of RPS3A is dependent on HPF1. We provide an ADPr-site Localization Spectra Database ADPr-LSD which contains 288 high-quality ADPr-modified peptide spectra to serve as ADPr spectral references for correct ADPr-site localizations.|
