FIGURE 4.
Effects of active site residue mutants on enzyme activity of BdsA. Activity is defined as the number of nmol of HBPSi produced min-1 nmol-1 in the presence of BdsA. Enzyme assays for all mutants were performed in the same way that the wild-type BdsA protein was tested. Error bars indicate the standard deviation of four repeats. The result figure was generated by origin pro 8.
