1prw Summary


Crystal structure of bovine brain Ca++ calmodulin in a compact form

The structure was published by Fallon, J.L. and Quiocho, F.A., in 2003 in a paper entitled "A closed compact structure of native ca(2+)-calmodulin." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.7 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 P62157 (CALM_BOVIN)search. The sample contained 149 residues which is 99% of the natural sequence. Out of 149 residues 149 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.
