Zif268 D20A Mutant Bound to WT DNA Site

The structure was published by Miller, J.C. and Pabo, C.O., in 2001 in a paper entitled "Rearrangement of side-chains in a Zif268 mutant highlights the complexities of zinc finger-DNA recognition." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 2001.

The experimental data on which the structure is based was not deposited.

This PDB entry contains a complex of 3 biomacromolecules, namely 5'-D(*AP*GP*CP*GP*TP*GP*GP*GP*CP*GP*G)-3', 5'-D(*TP*CP*CP*GP*CP*CP*CP*AP*CP*GP*C)-3', and ZIF268.

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.
