== Function ==
[[http://www.uniprot.org/uniprot/THIO_ECOLI THIO_ECOLI]] Participates in various redox reactions through the reversible oxidation of its active center dithiol to a disulfide and catalyzes dithiol-disulfide exchange reactions. [[http://www.uniprot.org/uniprot/DPOL_BPT7 DPOL_BPT7]] Replicates viral genomic DNA. Non-processive DNA polymerase that achieves processivity by binding to host thioredoxin (TrxA). This interaction increases the rate of dNTP incorporation to yield a processivity of approximately 800 nucleotides (nt) per binding event. Interacts with DNA helicase gp4 to coordinate nucleotide polymerization with unwinding of the DNA. The leading strand is synthesized continuously while synthesis of the lagging strand requires the synthesis of oligoribonucleotides by the primase domain of gp4.<ref>PMID:9218486</ref> <ref>PMID:21606333</ref>
