Synthetic inhibitors against the enzyme dipeptidyl peptidase (DPP)-IV, a serine protease implicated in the inactivation of incretin hormones, are currently used for the management of type 2 diabetes. The aim of the present study was to evaluate the potential of dietary proteins from various food commodities to serve as precursors of DPP-IV inhibitors by using an in silico approach. A total of 2256 fragments with peptide sequences matching those reported in the literature to present DPP-IV inhibitory activity were found in the 34 proteins that were investigated. Among those, Gly-Ala, Gly-Pro and Pro-Gly were the most frequently occurring sequences. Caseins from cow’s milk and collagens from bovine meat and salmon appeared to be the richest potential sources of DPP-IV inhibitors, whereas proteins from oat showed lower occurrence frequency values. This study suggests that dietary proteins could be used for generating DPP-IV inhibitory peptides.
► In silico study of dietary proteins as potential precursors of DPP-IV inhibitors.
► Both plant and animal proteins contain fragments with DPP-IV inhibitory activity.
► Sequences with inhibitory activity GA, GP and PG occurred with the highest frequency.
► Casein and collagen appear to be the richest potential sources of DPP-IV inhibitors.
