摘要：

An intracellular proteinase from Streatococcus cremoris was isolated, partially purified and characterized. A 40‐fold purification was obtained with retention of 73% of the original activity. The proteinase exhibited normal reaction kinetics with respect to enzyme concentration and reaction rate. Proteinase activity was optimal at pH 7.0 and 37°C. The enzyme showed maximum activity on casein, the alpha casein being preferentially degraded. Effect of metal ions, some inhibitors and reducing agents were studied.
