DNA polymerase II - Wikipedia
WEBDNA polymerase II (also known as DNA Pol II or Pol II) is a prokaryotic DNA-dependent DNA polymerase encoded by the PolB gene. [1] DNA Polymerase II is an 89.9-kDa protein and is a member of the B family of DNA polymerases.
DNA polymerase - Wikipedia
WEBDNA polymerase II is a family B polymerase encoded by the polB gene. Pol II has 3'–5' exonuclease activity and participates in DNA repair, replication restart to bypass lesions, and its cell presence can jump from ~30-50 copies per cell to ~200–300 during SOS induction. Pol II is also thought to be a backup to Pol III as it can interact ...
