Crystal structure of Ni-containing superoxide dismutase with Ni-ligation corresponding to the thiosulfate-reduced state

The structure was published by Wuerges, J., Lee, J.-W., Yim, Y.-I., Yim, H.-S., Kang, S.-O., and Djinovic Carugo, K., in 2004 in a paper entitled "Crystal structure of nickel-containing superoxide dismutase reveals another type of active site" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.1 Å and deposited in 2003.

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