Crystal structure of Ca2+/Calmodulin complexed with myristoylated CAP-23/NAP-22 peptide

The structure was published by Matsubara, M., Nakatsu, T., Kato, H., and Taniguchi, H., in 2004 in a paper entitled "Crystal structure of a myristoylated CAP-23/NAP-22 N-terminal domain complexed with Ca2+/calmodulin" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.3 Å and deposited in 2002.

The experimental data on which the structure is based was also deposited.

This PDB entry contains a complex of 2 biomacromolecules, namely CALMODULIN and CAP-23/NAP-22.

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.
