Different Residues on the Surface of the Methanothermobacter thermautotrophicus MCM Helicase Interact with Single- and Double-Stranded DNA

Figure 5

ATPase activity by the mutant MCM proteins. ATPase activities of wild-type and mutant MCM proteins were determined as described in “Section 2” using 30 nM of MCM (as monomer) in the presence or absence of 50 ng of ssDNA. The average results of three independent experiments with standard deviations are shown.
