QUERCETIN 2,3-DIOXYGENASE IN COMPLEX WITH THE INHIBITOR DIETHYLDITHIOCARBAMATE

The structure was published by Steiner, R.A., Kooter, I.M., and Dijkstra, B.W., in 2002 in a paper entitled "Functional Analysis of the Copper-Dependent Quercetin 2,3-Dioxygenase.1.Ligand-Induced Coordination Changes Probed by X-Ray Crystallography: Inhibition, Ordering Effect and Mechanistic Insights" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.7 Å and deposited in 2001.

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