Fig. 3From: Improving the thermostability of GH49 dextranase AoDex by site-directed mutagenesisEnzymatic properties of dextranase AoDex and its mutants. Relative activity is defined as the percentage of maximum enzymatic activity under the corresponding experimental conditions. a The optimal temperature of AoDex and mutants. The activities were determined at pH 7.0. b The optimal pH of AoDex and mutants. The activities were determined at 55 °CBack to article page
