Crystal structure of the C-terminal methionine sulfoxide reductase domain (MsrB) of N. gonorrhoeae pilB

The structure was published by Lowther, W.T., Weissbach, H., Etienne, F., Brot, N., and Matthews, B.W., in 2002 in a paper entitled "The mirrored methionine sulfoxide reductases of Neisseria gonorrhoeae pilB." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.85 Å and deposited in 2002.

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