Fig. 5: Molecular dynamics simulations of pol ι.
From: Visualizing DNA polymerase ι catalyze Hoogsteen-directed DNA synthesis
(A) Close-up of the active site of the pol ι-DNA-dTTP substrate complex with an overlay of 20 structures of the nascent base pair (shown as sticks) obtained after every 50 ns of simulation time for the first replicate. (B) Graph showing the glycosidic angle of the template nucleotide as a function of time. The shaded region (0 to 90°) represents the typical range for a Hoogsteen base pair. (C, D) Same as above for the pol ι complex bound to the pyrophosphate product. (E, F) Same as above for the pol ι complex bound to two monophosphate products. (G, H) Same as above for the pol ι complex bound to one monophosphate product. (I, J) Same as above for the pol ι binary product complex.
