THE 1.0 ANGSTROM CRYSTAL STRUCTURE OF CA+2 BOUND CALMODULIN

The structure was published by Wilson, M.A. and Brunger, A.T., in 2000 in a paper entitled "The 1.0 A crystal structure of Ca(2+)-bound calmodulin: an analysis of disorder and implications for functionally relevant plasticity" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.0 Å and deposited in 2000.

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

The PDB entry contains the structure of CALMODULIN. This molecule has the UniProt identifier P07463 (CALM_PARTE)search. The sample contained 148 residues which is 99% of the natural sequence. Out of 148 residues 146 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.
