چکیده انگلیسی
Methionine aminopeptidase (MetAP) is a promising target for the development of novel antibiotics. However, many potent inhibitors of the purified enzyme failed to show significant antibacterial activity. It is uncertain which divalent metal MetAP uses as its native cofactor in bacterial cells. Herein, we describe a cell-based assay that monitors the hydrolysis of a fluorogenic substrate by overexpressed MetAP in permeabilized Escherichia coli cells and its validation with a set of MetAP inhibitors. This cell-based assay is applicable to those cellular targets with poorly defined native cofactor, increasing the chances of identifying inhibitors that can inhibit the cellular target.
