Figure 2.
Hyperbolic fits for incorporation of dNTPs by pol η for different sequences. Filled circles correspond to B sequence, and empty circles to W sequence. (A) Correct incorporation of dATP opposite T. (B) Incorrect incorporation of dGTP opposite T. (C) Correct incorporation of dATP-CHF opposite T. (D) Incorrect incorporation of dGTP-CHF opposite T. For both the parent and the CHF analogue, the incorporation is sequence-independent for the correct incorporation (panels A and C) but very different for the misincorporation (panels B and D). In both cases, the W sequence results in a kpol for G opposite T significantly higher than that obtained with the B sequence while the Kd remains essentially unchanged.
