Crystal Structure of a mu-like calpain

The structure was published by Pal, G.P., Veyra, T.D., Elce, J.S., and Jia, Z., in 2003 in a paper entitled "Crystal Structure of a mu-like calpain reveals a partially activated conformation with low Ca(2+) requirement" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.8 Å and deposited in 2003.

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

This PDB entry contains multiple copies of the structure of mu-like calpain.
