1y6w Summary


Trapped intermediate of calmodulin

The structure was published by Grabarek, Z., in 2005 in a paper entitled "Structure of a Trapped Intermediate of Calmodulin: Calcium Regulation of EF-hand Proteins from a New Perspective." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.4 Å and deposited in 2004.

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 P62158 (CALM_HUMAN)search. The sample contained 148 residues which is 99% of the natural sequence. Out of 148 residues 145 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.
