Abstract
A fibrinolytic enzyme obtained from B. subtilis was purified, using DEAEβcellulose column chromatography, and gel filtration on Sephadex Gβ100. The preparation was homogeneous as tested by gel filtration on Sephadex Gβ200, and disc electrophoresis.
The molecular weight of this enzyme was 29.400 estimated by gel filtration on Sephadex Gβ100. The optimum pH for enzyme activity was 7.2. Copper ions significantly increased enzyme activity, while Zn^++^ and Mn^++^ caused marked inhibition.

BACKGROUND: Purification and enzymatic properties of a chitosanase from Bacillus subtilis RKY3 have been investigated to produce a chitooligosaccharide. The enzyme reported was extracellular and constitutive, which was purified by two sequential steps including ammonium sulfate precipitation and ion
