Purification of the crude enzyme was carried out in order of 60% saturated ammonium sulfate fractionation, heat treatment at 60℃ for 1hour, DEAE-TOYO Pearl L650, Buthyl Sepharose 4B columns chromatography and FPLC with RESOUCE Q, MONO Q and Superose 12 columns. Purified enzyme had 1071.71U/mg of specific activity, 0.14% of recovery, and 570 times of purification. The enzyme with molecular weight of about 50,000, maximum pH ranges of 7.5-8.5 and maximum temperature ranges of 5.5-6.5 showed homogeneity by electrophoresis.
