The local interactions that stabilize Tyr639 in the active site of the preinsertion complex with different nucleotides bound. The histograms are sampled from 10 to 100 ns in each individual simulation. (a) The interactions between Tyr639 and the end bp of the DNA-RNA hybrid. (b) The interactions between Tyr639 and the preinserted nucleotide, rATP, dATP, rGTP, rUTP, and rCTP.
