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.

This PDB entry contains multiple copies of the structure of Chitinase.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule has more than one probable quaternary state observed. For more details see the quaternary structure page.
