Figure 7

Substrate specifities of TraE, TraJ and TraK. TraE shows approximately the same activity with both ATP and TTP. Hydrolysis activity of TraJ is twofold with CTP as compared to ATP whereas TraK hydrolyzes TTP, ADP and ATP with approximately the same efficiency. ATPase activity of TraK is 50-60% lower with GTP and CTP than with ATP as a substrate. NTPase activity is given in nmol inorganic phosphate generated per min and per mg of the respective protein. The values are mean of three independent measurements with standard deviation.
