Abstract

The carnivorous plant Dionaea muscipula (Venus's flytrap) secretes proteinases into the digestive fluid to digest prey proteins. In this study, we obtained evidence that the digestive fluid contains a cysteine endopeptidase, presumably belonging to the papain family, through inhibitor studies and partial amino acid sequencing of the major SDS-PAGE band protein. The name "dionain" is proposed for the enzyme.

摘要

食肉植物捕蝇草（维纳斯捕蝇陷阱）会向消化液中分泌蛋白酶以消化猎物蛋白质。在本研究中，通过抑制剂研究以及对主要SDS-PAGE条带蛋白进行部分氨基酸测序，我们获得了证据，证明消化液中含有一种半胱氨酸内肽酶，可能属于木瓜蛋白酶家族。我们提议将该酶命名为“捕蝇草蛋白酶”。
