Effect on ultraviolet mutagenesis of genes 32, 41, 44, and 45 alleles of phage T4 in the presence of wild-type or antimutator DNA polymerase

Journal Article · · Virology; (United States)
Temperature-sensitive alleles of four genes whose products are essential for DNA elongation in phage T4 were tested for their effects on uv mutagenesis in the presence of an antimutator polymerase allele, tsCB87, or the wild-type polymerase allele. The results suggest that the products of genes 32, 41, 44, and 45, in addition to the gene 43 polymerase, influence the accuracy of the DNA synthesis associated with uv mutagenesis. When considered in combination with previous observations, it appears that thymine dimers in phase T4 DNA may cause mutation through an error-prone repair process which employs a multienzyme system involving at least five components in a replication step, and a final ligation step.
