Steady-state ATPase assays were performed by titrating the amount of nonradioactive ATP from 0.0375 to 100 μM. Vmax is indicated in units of nmol of ATP hydrolyzed·mg−1 of BiP·min−1. Km is indicated in units of μM. The R2 values from the linear regression were obtained as described in MATERIALS AND METHODS.
