1d4a Summary



The structure was published by Faig, M., Bianchet, M.A., Talalay, P., et al., Winski, S., Ross, D., and Amzel, L.M., in 2000 in a paper entitled "Structures of recombinant human and mouse NAD(P)H:quinone oxidoreductases: species comparison and structural changes with substrate binding and release." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.7 Å and deposited in 1999.

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