NMR SOLUTION STRUCTURE OF A COMPLEX OF CALMODULIN WITH A BINDING PEPTIDE OF THE CA2+-PUMP

The structure was published by Elshorst, B., Hennig, M., Forsterling, H., et al., Schmid, H., Vorherr, T., and Carafoli, E., in 1999 in a paper entitled "NMR solution structure of a complex of calmodulin with a binding peptide of the Ca2+ pump." (abstract).

The structure was determined using NMR spectroscopy and deposited in 1999.

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

This PDB entry contains a complex of 2 biomacromolecules, namely PROTEIN (CALMODULIN) and PROTEIN (CALCIUM PUMP).

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 most likely forms heterodimers.
