Description

4-Nitrophenyl 4'-guanidinobenzoate (NPGB) is a synthetic compound that has been studied extensively as a substrate for the enzyme chymotrypsin. It is a highly specific substrate for chymotrypsin, meaning that it is readily hydrolyzed by this enzyme but not by other proteases. This specificity makes NPGB a valuable tool for studying the kinetics and mechanism of chymotrypsin activity. NPGB is synthesized through a reaction of 4-nitrophenol with 4'-guanidinobenzoic acid. NPGB has been used to investigate the active site of chymotrypsin, the role of the catalytic triad (serine, histidine, and aspartate), and the mechanism of substrate binding and hydrolysis. The hydrolysis of NPGB by chymotrypsin is a two-step process: first, the enzyme binds to the substrate, and then the substrate is cleaved. NPGB has also been used to study the effects of inhibitors on chymotrypsin activity.'

Toxicity
