3iwr Summary


Crystal structure of class I chitinase from Oryza sativa L. japonica

The structure was published by Kezuka, Y., Kojima, M., Mizuno, R., Suzuki, K., Watanabe, T., and Nonaka, T., in 2010 in a paper entitled "Structure of full-length class I chitinase from rice revealed by X-ray crystallography and small-angle X-ray scattering." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.57 Å and deposited in 2009.

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