3.5.1.87 5 11 upon immobilization the operational pH range and temperature range are markedly broadened, ca. 35% relative activity at pH 5 for immoblized enzyme, 85% for free enzyme. At pH 11 ca. 60% relative activity for free enzyme and 50% for the immobilized enzyme is observed 3.5.1.87 5.5 9 - 3.5.1.87 5.5 9 activity range, profile overview 3.5.1.87 6 11 - 3.5.1.87 7 11 enzyme activity significantly decreases below, enzyme is highly active up to pH 11.0 3.5.1.87 7 9.5 -
