Enzymatic properties of Rpp20 (□) and human RNase P (●). Final concentration of enzyme was 7.5 μg/ml for Rpp20 and 40 μg protein/ml for human RNase P (MonoQ fraction). (A) Optimal temperature for ATPase activity. (B) Optimal pH for ATPase activity. The 1× ATPase buffer was replaced by 10 mM Bistris propane⋅HCl, 5 mM MgCl2, and 1 mM DTT. (C) Inhibition of ATPase activity by AMP-PNP.
