Fidelity of 3Dpol-Catalyzed Nucleotide Incorporation in the Presence of Mg2+ and Mn2+

---|---|---|---|
nucleotide | Mg2+ | Mn2+ | Mg2+/Mn2+ |
2′-dATP | 233 | 13 | 18 |
GTP | 15477 | 532 | 29 |
Fidelity is calculated as [(kpol/Kd,app)ATP + (kpol/Kd,app)incorrect]/[(kpol/Kd,app)incorrect] (41). sym/sub-U was employed; therefore, ATP is the correct nucleotide. The values for kpol/Kd,app in the presence of Mg2+ were obtained from ref 12, and those in the presence of Mn2+ were obtained from Table 1.
