CHEY MUTANT WITH LYS 91 REPLACED BY ASP, LYS 92 REPLACED BY ALA, ILE 96 REPLACED BY LYS AND ALA 98 REPLACED BY LEU (STABILIZING MUTATIONS IN HELIX 4)

The structure was published by Sola, M., Lopez-Hernandez, E., Cronet, P., et al., Serrano, L., Coll, M., and Parraga, A., in 2000 in a paper entitled "Towards understanding a molecular switch mechanism: thermodynamic and crystallographic studies of the signal transduction protein CheY." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 1996.

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

This PDB entry contains multiple copies of the structure of CHEY PROTEIN.

The molecule most likely forms homotetramers.
