ZIF268 ZINC FINGER-DNA COMPLEX

The structure was published by Elrod-Erickson, M., Rould, M.A., Nekludova, L., and Pabo, C.O., in 1996 in a paper entitled "Zif268 protein-DNA complex refined at 1.6 A: a model system for understanding zinc finger-DNA interactions." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.6 Å and deposited in 1997.

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

This PDB entry contains a complex of 3 biomacromolecules, namely DNA (5'-D(*AP*GP*CP*GP*TP*GP*GP*GP*CP*GP*T)-3'), DNA (5'-D(*TP*AP*CP*GP*CP*CP*CP*AP*CP*GP*C)-3'), and PROTEIN (ZIF268 ZINC FINGER PEPTIDE).

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.
