Function

[DPO1_ECOLI] In addition to polymerase activity, this DNA polymerase exhibits 3' to 5' and 5' to 3' exonuclease activity. It is able to utilize nicked circular duplex DNA as a template and can unwind the parental DNA strand from its template.

Publication Abstract from PubMed

The 3.3-A resolution crystal structure of the large proteolytic fragment of Escherichia coli DNA polymerase I complexed with deoxythymidine monophosphate consists of two domains, the smaller of which binds zinc-deoxythymidine monophosphate. The most striking feature of the larger domain is a deep crevice of the appropriate size and shape for binding double-stranded B-DNA. A flexible subdomain may allow the enzyme to surround completely the DNA substrate, thereby allowing processive nucleotide polymerization without enzyme dissociation.
