PDB entry 1ig5 (supersedes 5icb)

BOVINE CALBINDIN D9K BINDING MG2+

The structure was published by Andersson, M., Malmendal, A., Linse, S., Ivarsson, I., Forsen, S., and Svensson, L.A., in 1997 in a paper entitled "Structural basis for the negative allostery between Ca(2+)- and Mg(2+)-binding in the intracellular Ca(2+)-receptor calbindin D9k." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.5 Å and deposited in 2001.

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

The PDB entry contains the structure of VITAMIN D-DEPENDENT CALCIUM-BINDING PROTEIN, INTESTINAL. This molecule has the UniProt identifier P02633 (S100G_BOVIN)search. The sample contained 75 residues which is 95% of the natural sequence. Out of 75 residues 74 were observed and are deposited in the PDB.

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 is most likely monomeric.
