Table I. Potential acid phosphatase activity of the GST:AtPAP10 fusion protein

Activities were calculated relative to that of pNPP (taken as 100%). The specific activity of the GST:AtPAP10 fusion protein on pNPP was 497 μmol min−1 mg−1 protein. The control GST protein was not active on any of the listed compounds tested. ND, Not detected.
