Abstract

A purified heparinase I, II and III free of lyase activity and each having a molecular weight of 42,800 84,100, 70,800, respectively, are produced by culturing Flavobacterium heparinum. The kinetic properties of the heparinases have been determined as well as the conditions to optimize their activity and stability.
