1fgj Summary



The structure was published by Igarashi, N., Moriyama, H., Fujiwara, T., Fukumori, Y., and Tanaka, N., in 1997 in a paper entitled "The 2.8 A structure of hydroxylamine oxidoreductase from a nitrifying chemoautotrophic bacterium, Nitrosomonas europaea." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.8 Å and deposited in 1997.

The experimental data on which the structure is based was not deposited.
