海参(Stichopus japonicus)能够响应各种环境和机械信号而进行自溶。在对这一现象的长期研究框架内,我们通过使用 DE-52 纤维素的离子交换色谱法和使用 Sephadex G-100 的凝胶过滤色谱法从海参体壁中纯化了一种蛋白酶。最终的酶制剂在聚丙烯酰胺凝胶电泳上几乎是均质的,其分子量估计约为 35.5 kDa。纯化的酶在 pH 7.0 和 50°C 时表现出最大的酪蛋白水解活性,并在 pH 4.0–7.0 和 40–60°C 时表现出显着的稳定性。根据多种特异性蛋白酶抑制剂和激活剂获得的抑制和激活曲线,从海参体壁纯化的蛋白酶被定义为半胱氨酸样蛋白酶。
The sea cucumber (Stichopus japonicus) is able to undergo autolysis in response to a variety of environmental and mechanical cues. Within the framework of a long-term study of this phenomenon we have purified a protease from the body wall of the sea cucumber by means of ion-exchange chromatography with DE-52 cellulose and gel filtration chromatography with Sephadex G-100. The final enzyme preparation was nearly homogeneous on polyacrylamide gel electrophoresis, and its molecular weight was estimated to be approximately 35.5 kDa. The purified enzyme exhibited a maximum activity for the hydrolysis of casein at pH 7.0 and 50°C and a remarkable stability at pH 4.0–7.0 and 40–60°C. Based on the inhibition and activation profiles obtained with numerous specific protease inhibitors and an activator, the protease purified from the body wall of the sea cucumber was defined to be a cysteine-like protease.
