Primer extension reactions by family B DNA polymerases. (A) The reaction for ImON:NaNO base pair. (B) The reaction for ImNO:NaON base pair. All reactions used the primer-template combination 5′-FITC-GTTCTGGATGGTCAGCGCAC-3′ (20mer) and 3′-CAAGACCTACCAGTCGCGTGXGAACGGGTG-5′ (30mer, X = ImON, NaNO, ImNO or NaON). The reaction was carried out in the presence of dYTP (NaNOTP, ImONTP, NaONTP or ImNOTP) and natural dNTPs. Lane 1 indicates the 20-mer primer; lane 2 indicates the control 30mer prepared by primer extension reaction (X = T); lanes 3, 5, 7 and 9 indicate the results of Vent (exo); and lanes 4, 6, 8 and 10 indicate those of Deep Vent (exo) DNA polymerase.
