4fbu Summary


Dpo4 polymerase pre-insertion binary complex with the N-(deoxyguanosin-8-yl)-1-aminopyrene lesion

The structure was published by Kirouac, K.N., Basu, A.K., and Ling, H., in 2013 in a paper entitled "Structural mechanism of replication stalling on a bulky amino-polycyclic aromatic hydrocarbon DNA adduct by a y family DNA polymerase." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.6 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 IV, DNA primer, and DNA template.

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 has more than one probable quaternary state observed. For more details see the quaternary structure page.
