1du0 Summary



The structure was published by Grant, R.A., Rould, M.A., Klemm, J.D., and Pabo, C.O., in 2000 in a paper entitled "Exploring the role of glutamine 50 in the homeodomain-DNA interface: crystal structure of engrailed (Gln50 --> ala) complex at 2.0 A." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 2000.

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(*TP*TP*TP*TP*GP*CP*CP*AP*TP*GP*TP*AP*AP*TP*TP*AP*CP*CP*TP*AP*A)-3'), DNA (5'-D(*AP*TP*TP*AP*GP*GP*TP*AP*AP*TP*TP*AP*CP*AP*TP*GP*GP*CP*AP*AP*A)-3'), and ENGRAILED HOMEODOMAIN.

The molecule most likely forms heterotetramers.
