FIGURE 6.
Effects of PC on the GTPase activity of FtsZ (10 μm), with 1 mm GTP and 10 mm MgCl2, pH 6.8 at 25 °C. Bs-FtsZ: solid circles, Hepes50; triangles, Hepes250; squares, Mes50. Ec-FtsZ: open circles, Hepes50 (average of three different protein preparations). The lines are drawn solely to show the trend of the data. The increase in GTPase activity of Ec-FtsZ was confirmed by measurements at varying protein concentrations with excess 15 μm PC (not shown).
