4elv Summary


Snapshot of the large fragment of DNA polymerase I from Thermus Aquaticus processing modified pyrimidines

A publication describing this structure is not available. The depositing authors are Marx, A.search; Diederichs, K.search; Obeid, S.search

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 2012.

The experimental data on which the structure is based was also deposited.

This PDB entry contains a complex of 3 biomacromolecules, namely DNA polymerase I, thermostable, DNA (5'-D(*GP*AP*CP*CP*AP*CP*GP*GP*CP*GP*CP*(0R8))-3'), and DNA (5'-D(*AP*AP*AP*GP*GP*GP*CP*GP*CP*CP*GP*TP*GP*GP*TP*C)-3').

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule most likely forms heterotrimers.
