Figure 9. Model of a possible ternary complex of Pfu:E10: DNA:Cy5-dCTP.

Figure 9

A). Each domain from the binary PFu:E10:DNA structure was superimposed separately onto the corresponding domain from the RB69:DNA:dTTP ternary complex, and coloured as for Figure 3. A molecule of Cy5-dCTP was then modelled into this with green carbon, red oxygen, blue nitrogen, yellow sulphur and purple phosphorous atoms, to try to understand how such a large molecule could fit into the complex. There appears to be a channel between the Fingers, Thumb and Exonuclease domains into which the large Cy5 molecule could extend. B). Representation of Cy5-dCTP.
