Dual-labeling of ubiquitin proteins by chemoselective reactions for sensing UCH-L3†
Abstract
A site-specific dual-color labeled ubiquitin for sensing deubiquitinase's activity was prepared by consecutively using chemoselective native chemical ligation reactions in a facile and efficient way. The prepared sensor was applied to establish a sensitive FRET-based assay for UCH-L3.
