Crystal structure of the DBD domain of human DNA ligase IV bound to Artemis peptide

The structure was published by De Ioannes, P., Malu, S., Cortes, P., and Aggarwal, A.K., in 2012 in a paper entitled "Structural Basis of DNA Ligase IV-Artemis Interaction in Nonhomologous End-Joining." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.2502 Å and deposited in 2012.

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

This PDB entry contains a complex of 2 biomacromolecules, namely DNA ligase 4 and Protein artemis.

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