ectoATPase activity of EMS-generated M. hominis oppA-mutants. ectoATPase activity of EMS-generated Mho369 and Mho940 M. hominis mutants and of M. hominis PG21 parental strain was determined by measuring the release of free phosphate per 1010 cells as a function of the ATP concentration. The data represent the means and standard errors of five (Mho369) and four (Mho940 and PG21) independent experiments with triplicate samples in each experiment.
