Crystal Structure of Human ADP-ribose Transferase ARTD15/PARP16 Reveals a Novel Putative Regulatory Domain.
J.Biol.Chem., 287:24077-24081, 2012

PubMed Abstract: ADP-ribosylation is involved in the regulation of DNA repair, transcription, and other processes. The 18 human ADP-ribose transferases with diphtheria toxin homology include ARTD1/PARP1, a cancer drug target. Knowledge of other family members may guide therapeutics development and help evaluate potential drug side effects. Here, we present the crystal structure of human ARTD15/PARP16, a previously uncharacterized enzyme. ARTD15 features an α-helical domain that packs against its transferase domain without making direct contact with the NAD(+)-binding crevice or the donor loop. Thus, this novel domain does not resemble the regulatory domain of ARTD1. ARTD15 displays auto-mono(ADP-ribosylation) activity and is affected by canonical poly(ADP-ribose) polymerase inhibitors. These results add to a framework that will facilitate research on a medically important family of enzymes.
