GTPase Activity of YqeH Mutants.

Specific activity was measured in the presence of KCl and it is represented as the amount of Pi released for a given concentration of enzyme for a certain time (min). Value for wild type was taken from Table 1. Experiments were conducted in duplicates and were reproduced at least twice. The errors represent the standard deviation from the average. Values were corrected for the background intrinsic GTP hydrolysis. ** indicates that the activity could not be measured.
