A novel, nontoxic, proteinaceous trypsin inhibitor was reported from seeds of Albizia amara.
The purified proteinaceous protease inhibitor (API) is a thermo- and salt-stable 49-kDa protein.
API has antifungal activity against Alternaria alternata, Alternaria tenuissima, and Candida albicans.
API has antibacterial activity against Pseudomonas aeruginosa and Bacillus subtilis.
API has potential to inhibit trypsin, chymotrypsin, and proteinase-K.
