Key Concepts: Bacterial DNA polymerase I enzymes are multidomain proteins with separate polymerisation, proofreading and 5â²â3â² exonuclease functions. They perform a vital function in bacteria by carrying out DNA repair and some aspects of chromosomal replication.
NS1 is essential for replication of the virus genome  but it is not a DNA polymerase. Instead, NS1 acts as an origin recognition protein, which specifically binds to double-stranded virus DNA and allows host DNA polymerase to replicate viral DNA, generating many single-stranded copies of the parvovirus genome.
