  The post-translational modification (PTM) and signaling molecule poly(ADP-ribose) (PAR) has an impact on diverse biological processes. PTM is regulated by a series of ADP-ribosyl glycohydrolases (PARG enzymes) that cleave polymers and/or liberate monomers from their protein targets. Disclosed herein is a substrate for monitoring PARG activity, TFMU-ADPr, which directly reports on total PAR hydrolase activity via release of a fluorophore; this substrate has excellent reactivity, generality, stability, and usability. A second substrate, TFMU-IDPr, selectively reports on PARG activity only from the enzyme ARH3. Use of these probes in whole-cell lysate experiments has revealed a mechanism by which ARH3 is inhibited by cholera toxin. TFMU-ADPr and TFMU-IDPr are versatile tools for assessing small-molecule inhibitors in vitro and probing the regulation of ADP-ribosyl catabolic enzymes.

  翻译结果：翻译后修饰（PTM）和信号分子聚腺苷二磷酸核糖（PAR）对多种生物过程产生影响。PTM受一系列ADP核糖水解酶（PARG酶）调控，这些酶从它们的蛋白靶标中切割聚合物和/或释放单体。本文披露了一种用于监测PARG活性的底物，TFMU-ADPr，它通过释放荧光团直接报告总PAR水解酶活性；该底物具有出色的反应性、普适性、稳定性和可用性。第二种底物TFMU-IDPr，只选择性地报告来自酶ARH3的PARG活性。在全细胞裂解液实验中使用这些探针揭示了一种由霍乱毒素抑制ARH3的机制。TFMU-ADPr和TFMU-IDPr是评估体外小分子抑制剂和探究ADP核糖降解酶调控的多功能工具。
