Polyserase-3 may form active dimers. A, Western blot analysis of His-tagged polyserase-3 in the absence (-) or presence (+) of 2% 2-mercaptoethanol, using an anti-HisTag antibody. Molecular size markers are indicated on the right, and detected bands are indicated with arrows on the left. B, degradation of fibrinogen by His-tagged polyserase 3 in the absence or presence of the serine protease inhibitor AEBSF.
