Polymerases:

T4 A777V,T4,T4 A737V,T4 A89TD363N,T4 F868S,T4 S345P

Topics:

Mutational Analysis, Fidelity, Nucleotide Incorporation, Exonuclease Activity

One line summary:

Spontaneous mutation rate is related to the relative rates of insertion and removal of nucleotides during DNA synthesis; mutations in T4 DNA polymerase which perturb the exonuclease to polymerase ratio result in mutator or antimutator polymerases.
