1iq5 Summary


Calmodulin/nematode CA2+/Calmodulin dependent kinase kinase fragment

The structure was published by Kurokawa, H., Osawa, M., Kurihara, H., et al., Swindells, M.B., Kainosho, M., and Ikura, M., in 2001 in a paper entitled "Target-induced conformational adaptation of calmodulin revealed by the crystal structure of a complex with nematode Ca(2+)/calmodulin-dependent kinase kinase peptide" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.8 Å and deposited in 2001.

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

This PDB entry contains a complex of 2 biomacromolecules, namely CALMODULIN and CA2+/CALMODULIN DEPENDENT KINASE KINASE.

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.
