ABSTRACT
Cellular redox conditions affect Gsp amidase activity in Escherichia coli. Guided by the structure and catalytic mechanism of the amidase, we designed and synthesized an acyloxymethyl ketone-based activity probe containing a biotin handle. This probe was used to monitor Gsp amidase activity in E. coli lysates that had been subjected to oxidative or methylglyoxal-induced stress.
