4icb Summary



The structure was published by Svensson, L.A., Thulin, E., and Forsen, S., in 1992 in a paper entitled "Proline cis-trans isomers in calbindin D9k observed by X-ray crystallography." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.6 Å and deposited in 1991.

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

The PDB entry contains the structure of CALBINDIN D9K. This molecule has the UniProt identifier P02633 (S100G_BOVIN)search. The sample contained 76 residues which is 95% of the natural sequence. Out of 76 residues 75 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.
