Reduced mutant D98N of AfNiR exposed to nitric oxide

The structure was published by Tocheva, E.I., Rosell, F.I., Mauk, A.G., and Murphy, M.E., in 2007 in a paper entitled "Stable copper-nitrosyl formation by nitrite reductase in either oxidation state" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.65 Å and deposited in 2007.

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

This PDB entry contains multiple copies of the structure of Copper-containing nitrite reductase.

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 homotrimers.
