CALPAIN DOMAIN VI APO

The structure was published by Blanchard, H., Grochulski, P., Li, Y., et al., Davies, P.L., Elce, J.S., and Cygler, M., in 1997 in a paper entitled "Structure of a calpain Ca(2+)-binding domain reveals a novel EF-hand and Ca(2+)-induced conformational changes." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.3 Å and deposited in 1997.

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