ABSTRACT
Here, we present the first quantitative method for the activity analysis of protealysin-like protease (PLP) inhibitors. This approach is based on a previously developed method for protealysin activity determination by hydrolysis of internally quenched fluorescent peptide substrate 2-aminobenzoyl-L-arginyl-L-seryl-L-valyl-L-isoleucyl-L-(ε-2,4-dinitrophenyl)lysine. In this protocol, we significantly reduced enzyme concentration and introduced some minor modifications to decrease variation between replicates. The protocol was validated using emfourin, a novel proteinaceous metalloprotease inhibitor. Data obtained demonstrates that the developed assay method is an affordable approach for characterizing and screening various PLP inhibitors. Graphical abstract.
