1aq8 Summary



The structure was published by Murphy, M.E., Turley, S., and Adman, E.T., in 1997 in a paper entitled "Structure of nitrite bound to copper-containing nitrite reductase from Alcaligenes faecalis. Mechanistic implications." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 1997.

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

This PDB entry contains multiple copies of the structure of 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.
