the purified enzyme showed characteristics of a trypsin-like serine protease ( labeling with [ 3h ] diisopropylphosphorofluoridate which was prevented by p-nitrophenyl-p'-guanidinobenzoate ) and converted the single chain of human plasminogen into two chains of plasmin with electrophoretic mobilities identical to those of the chains formed by non-purified enzyme and by human urokinase .
