PDB entry 1fw4 (supersedes 1trc)

CRYSTAL STRUCTURE OF E. COLI FRAGMENT TR2C FROM CALMODULIN TO 1.7 A RESOLUTION

The structure was published by Olsson, L.L. and Sjolin, L., in 2001 in a paper entitled "Structure of Escherichia coli fragment TR2C from calmodulin to 1.7 A resolution." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.7 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 P62157 (CALM_BOVIN)search. The sample contained 71 residues which is < 90% of the natural sequence. Out of 71 residues 65 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.
