The bacteriophage T4 dexA gene: sequence and analysis of a gene conditionally required for DNA replication.

We have cloned and sequenced a bacteriophage T4 EcoRI fragment that complements T4 del (39-56) infections of an optA defective Escherichia coli strain. Bacteria containing this recombinant plasmid synthesize two new proteins with molecular weights of 9 and 26 kilodaltons. We have identified the gene encoding the 26 kilodalton protein as essential for T4 infections of optA defective E. coli. Genetic and biochemical results are consistent with the identification of this protein as the product of the dexA gene, which encodes a 3' to 5' exonuclease.[1]
