Molecular Dynamics Study of the Opening Mechanism for DNA Polymerase I
Figure 4
A histogram of the Pro699-Arg629 α-C distances for the 1.0 µs simulation (10,000 frames total) of PDB 1LV5 performed with Desmond using the Charmm27 force field.
The histogram clearly shows three distinct conformations were sampled: closed (C), open (O), and the newly observed intermediate (I) state.
