Comparison of ATPase activity of the p140K656A mutant hRFC, wt hRFC, and wt p40·p37·p36 complex

Protein	ATP hydrolyzed per molecule of protein per min
	−DNA	+DNA
Mutant hRFC	0.34	5
wt hRFC178	2.4	19.5
wt p40·p37·p36*	0.15	4.5

¹⁷⁸The ATPase activities of the wt hRFC and the wt p40·p37·p36 complex are similar to those reported previously (8, 12).
