FIG. 1.

Effects of suppressor mutations on kinetics of PAI2-AP export upon induction with arabinose. The two suppressor mutations of strains SB1 and SB34 were transduced into the parental strain SB0, generating suppressor strains SB01 and SB034, respectively. All strains express the chimeric PAI2-AP protein. Cells grown to an A₆₀₀ of 0.1 in NZ medium at 37°C were induced with 0.2% arabinose at time zero. AP activity was assayed at the indicated times. Each curve represents the average of three independent cultures; error bars indicate standard deviations.
