Activities of nSPE B/SCP and rSPE B/SCP. The cysteine protease activity that originated from SPE B/SCP was detected as caseinolytic activity. (A) The SCP activity of rSPE B/SCP (solid squares) was the same as or higher than that of nSPE B/SCP (open circles). (B) The cysteine protease-specific inhibitors E64 (open squares) and Box-LVG-CHN2 (solid triangles) inhibited rSPE B/SCP activity.
