Crystal structure of chitinase C from Streptomyces griseus HUT6037

The structure was published by Kezuka, Y., Ohishi, M., Itoh, Y., et al., Mitsutomi, M., Watanabe, T., and Nonaka, T., in 2006 in a paper entitled "Structural Studies of a Two-domain Chitinase from Streptomyces griseus HUT6037" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 3.14 Å and deposited in 2005.

The experimental data on which the structure is based was not deposited.
