Abstract

The isolation and preliminary characterization of a trypsin-like protease with high activity at 20 degrees C is described. This protease was isolated from Antarctic krill (Euphasia superba) by a two-step chromatography process and the use of zymogram analyses. The protease has a molecular weight of 30 kDa and a pI of 4.1. Its specific activity at 20 degrees C on BAPNA is 0.5 U/mg.

海洋源性低温蛋白酶的分离纯化及初步鉴定。
本文描述了一种在20℃下具有高活性的胰蛋白酶样蛋白酶的分离和初步鉴定。采用两步色谱法和酶谱法从南极磷虾(Euphasia superba)中分离得到该蛋白酶。该蛋白酶分子量为30 kDa, pI为4.1。在20℃时对BAPNA的比活性为0.5 U/mg。
