It is observed that among the three peptides analyzed, the Gor 5 presented lower inhibition constant and therefore, the most potent among the tested ones. The predominance of hydrophobic residues in the region of the secondary site of the enzymes favored the interaction of the peptide. After characterization by three different types of graphs profiles, it is possible to verify that the inhibition model of the trypsin-like enzymes for the tested peptides is of the linear competitive type, in the concentration range of inhibitors and substrates analyzed. However, by the graphing profiles it is observed that the inhibition occurred due to the interaction of the peptides at the secondary site S2' in the hydrophobic cavity of the enzymes analyzed.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
