CALCIUM-FREE CALMODULIN

The structure was published by Kuboniwa, H., Tjandra, N., Grzesiek, S., Ren, H., Klee, C.B., and Bax, A., in 1995 in a paper entitled "Solution structure of calcium-free calmodulin." (abstract).

The structure was determined using NMR spectroscopy and deposited in 1995.

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 P62155 (CALM_XENLA)search. The sample contained 148 residues which is 99% of the natural sequence. Out of 148 residues 148 were observed and are deposited in the PDB.

The molecule is most likely monomeric.
