1ahr Summary



The structure was published by Tabernero, L., Taylor, D.A., Chandross, R.J., et al., Means, A.R., Quiocho, F.A., and Sack, J.S., in 1997 in a paper entitled "The structure of a calmodulin mutant with a deletion in the central helix: implications for molecular recognition and protein binding." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.8 Å and deposited in 1997.

The experimental data on which the structure is based was not deposited.

The PDB entry contains the structure of CALMODULIN. This molecule has the UniProt identifier P62149 (CALM_CHICK)search. The sample contained 146 residues which is 98% of the natural sequence. Out of 146 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.
