There are various kinds of carnivorous plants in nature, and most of them excrete acidic digestive fluids which contain digestive enzymes, especially acidic proteinases, to digest trapped insects and other prey for nutrition (Juniper et al. 1989). Previous inhibitor studies (Lobareva et al. 1973; Takahashi et al. 1974; Tökés et al. 1974) indicated that the acid proteinase nepenthesin from Nepenthes belongs to the aspartic proteinase family. Recently, we purified two nepenthesins from the… CONTINUE READING
