+ | [[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> [[http://www.uniprot.org/uniprot/THIO_ECO57 THIO_ECO57]] Participates in various redox reactions through the reversible oxidation of its active center dithiol to a disulfide and catalyzes dithiol-disulfide exchange reactions (By similarity). [[http://www.uniprot.org/uniprot/PRIM_BPT7 PRIM_BPT7]] Synthesizes short RNA primers for DNA replication. Unwinds the DNA at the replication forks and generates single-stranded DNA for both leading and lagging strand synthesis. The primase synthesizes short RNA primers on the lagging strand that the polymerase elongates using dNTPs.<ref>PMID:9096333</ref> <ref>PMID:21606333</ref> <ref>PMID:22977246</ref> | ||
