p‐Formyl‐phenyl phosphate was identified as a generic substrate for protein tyrosine phosphatases (PTPs) and was used to scrutinize the proteins' secondary binding site for specifically binding fragments. Binding fragments were detected by an amplified turnover of the substrate in a dynamic ligation reaction and were developed to highly specific PTP inhibitors.
研究第二个位点: 对磷酸甲酰苯酯被确定为蛋白质酪氨酸磷酸酶(PTP)的通用底物,并用于检查蛋白质的次级结合位点以特异性结合片段。通过在动态连接反应中扩增底物的周转来检测结合片段,并将其发展为高度特异性的PTP抑制剂。
