 note = {Gelatinase in the culture supernatant of Prevotella intermedia was purified to homogeneity by the combined procedure of ethanol precipitation and three steps of chromatography. The enzyme was a cystein protease with a molecular mass of 45 kDa. The activity was inhibited by divalent metal chelators and its inhibition was recovered by the addition of Ca^<2+>. The optimum pH for activity was 7.0-7.5 and the enzyme was inactivated by heating at 60℃ for 10 min. It hydrolyzed actively azocoll and hide powder besides gelatin. Hydrolysis of type IV collagen, if not strong, was also observed., application/pdf},
