--- In the present research some biochemical and biological characteristics of a hyaluronidase from the venom of Lachesis muta snake were evaluated. In this way the method for purification of this enzyme was improved. 50 mg of whole venom was disolved in 0.05 M amoniun acetate buffer pH 5.0 and applied to Sephadex G-100 gel filtration chromatography followed by CM Sephadex C-50 exchange chromatography using the same buffer. In the last system, the enzyme was recovered after a gradient of NaCl from 0 to 0,7 M with 51,4 folds and 39,02% of yield. The hyaluronidase was achieved as homogeneus band of protein by PAGE-SDS with 65 kDa of molecular weigth. The enzyme registered 5,0 as optimus pH, Km: 34,4 µg of hyaluronic acid/ml and Vmax: 40.9 µg hidrolizade hyaluronic acid/minute/mg. The enzyme showed a total dependence for Cl- and Br- ions. The biological activity assays using agar-blood plates showed the hyaluronidase was a spreading factor, because of hemolisis by phospholipase A2 ocurred using the total venom. In addition, any biological effect was observed after inoculation of 0,4 to 1,6 mg of the hyaluronidase on mice.
