title = "Structure of mammalian poly(ADP-ribose) glycohydrolase reveals a flexible tyrosine clasp as a substrate-binding element",
abstract = "Reversible post-translational modification by poly(ADP-ribose) (PAR) regulates chromatin structure, DNA repair and cell fate in response to genotoxic stress. PAR glycohydrolase (PARG) removes PAR chains from poly ADP-ribosylated proteins to restore protein function and release oligo(ADP-ribose) chains to signal damage. Here we report crystal structures of mammalian PARG and its complex with a substrate mimic that reveal an open substrate-binding site and a unique 'tyrosine clasp' enabling endoglycosidic cleavage of branched PAR chains.",
