Inhibitory effects of a Kunitz-type inhibitor from Pithecellobium dumosum (Benth) seeds against insect-pests' digestive proteinases.

Pithecellobium dumosum is a tree belonging to the Mimosoideae subfamily that presents various previously characterized Kunitz-type inhibitors. The present study provides a novel Kunitz-trypsin inhibitor isoform purified from P. dumosum seeds.
