Fig. 5From: Cloning and characterization of filamentous temperature-sensitive protein Z from Xanthomonas oryzae pv. Oryzae Effect of pH on the GTPase activity of the recombinant FtsZ. The effect of pH on GTPase activity of the recombinant FtsZ was determined by the GTPase activity assay with 5 mM GTP as substrate in the pH range of 4.0–10.0 at 50 °C. The relative GTPase activity of the recombinant FtsZ is the ratio of the GTPase activity at a certain pH and at optimum pHBack to article page
