1nir Summary



The structure was published by Nurizzo, D., Silvestrini, M.C., Mathieu, M., et al., Brunori, M., Tegoni, M., and Cambillau, C., in 1997 in a paper entitled "N-terminal arm exchange is observed in the 2.15 A crystal structure of oxidized nitrite reductase from Pseudomonas aeruginosa." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.15 Å and deposited in 1997.

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