Figure 4From: Characterization of a chemostable serine alkaline protease from Periplaneta americanaEffect of inhibitors on the activity of purified P. americana protease. Different inhibitors were pre-incubated with the purified enzyme for 30 min at 40°C and assay was carried out using casein as substrate. The activity of enzyme without inhibitor was considered as 100%. The error bars show the standard deviation of at least tree replicates.Back to article page
