inga bella/protease

A 6.5 kDa serine protease inhibitor was purified by anion-exchange chromatography from the crude extract of the Inga umbratica seeds, containing inhibitor isoforms ranging from 6.3 to 6.7 kDa and protease inhibitors of approximately 19 kDa. The purified protein was characterized as a potent

Plant protease inhibitors (PIs) are elements of a common plant defense mechanism induced in response to herbivores. The fall armyworm, Spodoptera frugiperda, a highly polyphagous lepidopteran pest, responds to various PIs in its diet by expressing genes encoding trypsins. This raises the question of

Inga laurina is a tree that belongs to the Mimosoideae sub-family of the Leguminosae. A protein inhibitor of trypsin (ILTI) was isolated from its seeds by ammonium sulphate precipitation, ion-exchange chromatography and rechromatography on an HiTrap Q ion-exchange column. By SDS-PAGE, ILTI yielded a

Digestive endoprotease activities of the coconut palm weevil, Homalinotus coriaceus (Coleoptera: Curculionidae), were characterized based on the ability of gut extracts to hydrolyze specific synthetic substrates, optimal pH, and hydrolysis sensitivity to protease inhibitors. Trypsin-like proteinases

Protease inhibitors have a broad biotechnological application ranging from medical drugs to anti-microbial agents. The Inga laurina trypsin inhibitor (ILTI) previously showed a great in vitro inhibitory effect under the adherence of Staphylococcus species, being a strong candidate for use as an
