Comparative analysis of mycobacterial protein tyrosine phosphatases. (A) (i) Steady-state kinetics of rMTBPtpA and (ii) steady-state kinetics of rMIPPtpB were determined using the pNPP assay. The rate of substrate (pNPP) hydrolysis is plotted against increasing substrate concentrations. Data represent the mean ± SD of three independent experiments.
