What is dna polymerase 2?

DNA polymerase II is a type of DNA polymerase enzyme found in bacteria, particularly in E. coli. It is involved in DNA repair processes, including base excision repair and nucleotide excision repair. DNA polymerase II has proofreading capabilities, allowing it to correct errors in newly synthesized DNA strands. It is also known to assist in DNA replication in certain situations where the main replicative polymerase, DNA polymerase III, encounters obstacles or damage in the DNA template. DNA polymerase II is encoded by the polB gene in E. coli and belongs to the Y-family of DNA polymerases.
