Crystal Structure of Potato Calmodulin PCM6

The structure was published by Yun, C.H., Bai, J., Sun, D.Y., Cui, D.F., Chang, W.R., and Liang, D.C., in 2004 in a paper entitled "Structure of potato calmodulin PCM6: the first report of the three-dimensional structure of a plant calmodulin." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 2003.

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 Q7DMN9 (CALM5_SOLTU)search. The sample contained 149 residues which is 100% of the natural sequence. Out of 149 residues 147 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.
