Abstract Bacteriophage RB69 encodes a replicative B-family DNA polymerase (RB69 gp43) with an associated proofreading 3′ exonuclease. Crystal structures have been determined for this enzyme with and without DNA substrates. We previously described the mutation rates and kinds of mutations produced in vivo by the wild-type (Pol+ Exo+) enzyme, an exonuclease-deficient mutator variant (Pol+ Exo-), mutator variants with substitutions at Tyr567 in the polymerase active site (PolM Exo+), and the double mutator PolM Exo-. Comparing the mutational spectra of the Pol+ Exo- and Pol+ Exo+ enzymes revealed the patterns and efficiencies of proofreading, while Tyr567 was identified as an important determinant of base-selection fidelity. Here, we sought to determine how well the fidelities of the same enzymes are reflected in vitro. Compared to their behavior in vivo, the three mutator polymerases exhibited modestly higher mutation rates in vitro and their mutational predilections were also somewhat different. Although the RB69 gp43 accessory proteins exerted little or no effect on total mutation rates in vitro, they strongly affected mutation rates at many specific sites, increasing some rates and decreasing others.
