Crystal structure of Mg(2+) and BeF(3)(-)-bound CheY in complex with CheZ(200-214) solved from a F432 crystal grown in CAPS (pH 10.5)

The structure was published by Guhaniyogi, J., Robinson, V.L., and Stock, A.M., in 2006 in a paper entitled "Crystal Structures of Beryllium Fluoride-free and Beryllium Fluoride-bound CheY in Complex with the Conserved C-terminal Peptide of CheZ Reveal Dual Binding Modes Specific to CheY Conformation." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 2006.

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

This PDB entry contains a complex of 2 biomacromolecules, namely Chemotaxis protein cheY and C-terminal 15-mer from Chemotaxis protein cheZ.

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 has more than one probable quaternary state observed. For more details see the quaternary structure page.
