Crystal structure of H145A mutant of nitrite reductase from Alcaligenes faecalis

The structure was published by Wijma, H.J., Boulanger, M.J., Molon, A., et al., Murphy, M.E., Verbeet, M.P., and Canters, G.W., in 2003 in a paper entitled "Reconstitution of the type-1 active site of the H145G/A variants of nitrite reductase by ligand insertion" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 2003.

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.
