Crystal structure of des(1-52)grancalcin with bound calcium

The structure was published by Jia, J., Borregaard, N., Lollike, K., and Cygler, M., in 2001 in a paper entitled "Structure of Ca(2+)-loaded human grancalcin." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.7 Å and deposited in 2001.

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

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

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 most likely forms homodimers.
