The activity of recombinant serine protease was analyzed. The results showed that the recombinant serine protease gene was 1 062 bp, encoding 352 amino acids ; the optimal reaction temperature for recombinant serine protease was 50 ℃, and the optimal pH was 5. 0. The serine protease could be developed into a new tool enzyme in biological engineering and food processing.展开更多
