CRYSTAL STRUCTURES OF THE KLENOW FRAGMENT OF DNA POLYMERASE I COMPLEXED WITH DEOXYNUCLEOSIDE TRIPHOSPHATE AND PYROPHOSPHATECRYSTAL STRUCTURES OF THE KLENOW FRAGMENT OF DNA POLYMERASE I COMPLEXED WITH DEOXYNUCLEOSIDE TRIPHOSPHATE AND PYROPHOSPHATE

Structural highlights

1kfd is a 1 chain structure with sequence from Escherichia coli. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 3.9Å
Ligands:
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

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.

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
