Crystal Structure of Bacillus Subtilis Probable Glutaminase, APC1040

The structure was published by Brown, G., Singer, A., Proudfoot, M., et al., Joachimiak, A., Savchenko, A., and Yakunin, A.F., in 2008 in a paper entitled "Functional and structural characterization of four glutaminases from Escherichia coli and Bacillus subtilis." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 2002.

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