PDB entry 1ksm (supersedes 1k31)

AVERAGE NMR SOLUTION STRUCTURE OF CA LN CALBINDIN D9K

The structure was published by Bertini, I., Donaire, A., Jimenez, B., et al., Parigi, G., Piccioli, M., and Poggi, L., in 2001 in a paper entitled "Paramagnetism-based versus classical constraints: an analysis of the solution structure of Ca Ln calbindin D9k." (abstract).

The structure was determined using NMR spectroscopy and deposited in 2002.

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. This molecule has the UniProt identifier P02633 (S100G_BOVIN)search. The sample contained 79 residues which is 100% of the natural sequence. Out of 79 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.
