ApV1 displays indistinguishable optimal temperature and pH activities to AppA phytase. Optimal temperature (a) and pH (b) curves for ApV1 and AppA phytases. Phytase activity was determined by the p-NPP assay at 37 °C. Percentage of maximum activity was calculated as a percentage of phytase activity at the optimal temperature or pH. Data are represented as mean values ± standard deviation (n = 3)
