Abstract

Taking PAR apart Proteins can be reversibly modified through the addition of repeating, polymerized ADP-ribose (PAR) subunits catalysed by poly(ADP-ribose) polymerase (PARP). Removal of PAR requires a glycohydrolase (PARG), which cleaves the ribose–ribose bond between subunits. Ivan Ahel and colleagues report that bacteria and fungi have a divergent PARG, which is unrelated to other enzymes that cleave PAR. Its structure, in complex with ADP-ribose and with a PARG inhibitor, and the results of mutational analysis suggest that the mechanism used in mammals and bacteria may be conserved. PARP inhibitors are being developed as pharmaceuticals for diseases including cancer, and this work suggests that small, cell-permeable PARG inhibitors might also be possible drug candidates.
