WILD TYPE CEL6A WITH A NON-HYDROLYSABLE CELLOTETRAOSE

The structure was published by Zou, J.-Y., Kleywegt, G.J., Stahlberg, J., et al., Koivula, A., Teeri, T.T., and Jones, T.A., in 1999 in a paper entitled "Crystallographic Evidence for Substrate Ring Distortion and Protein Conformational Changes During Catalysis in Cellobiohydrolase Cel6A from Trichoderma Reesei" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 1999.

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