This paper describes a new fluorescent chemosensor for phosphorylated peptide, which comprises a rigid trans-4,4′-diazastilbene and two Zn(II)-Dpa (2,2′-dipicolylamine) units; this chemosensor sequence-selectively binds to a (i, i + 1) bis-phosphorylated peptide and displays a dual-emission fluorescence change.
本文介绍了一种新的磷酸化肽荧光化学传感器,它由一个刚性反式-4,4′-二氮杂二苯乙烯和两个 Zn(II)-Dpa (2,2′-二二甲胺)单元组成;这种化学传感器序列选择性地与 (i, i + 1) 双磷酸化肽结合,并显示双发射荧光变化。
