STRUCTURE OF RESTRICTION ENDONUCLEASE FOKI BOUND TO DNA

The structure was published by Wah, D.A., Hirsch, J.A., Dorner, L.F., Schildkraut, I., and Aggarwal, A.K., in 1997 in a paper entitled "Structure of the multimodular endonuclease FokI bound to DNA." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.8 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(*TP*CP*GP*GP*AP*TP*GP*AP*TP*AP*AP*CP*GP*CP*TP*AP*G P*TP*CP*A)-3'), DNA (5'-D(*AP*TP*GP*AP*CP*TP*AP*GP*CP*GP*TP*TP*AP*TP*CP*AP*T P*CP*CP*G)-3'), and PROTEIN (FOKI RESTRICTION ENDONUCLEASE).

The molecule most likely forms heterotrimers.
