Crystal structure of Fus3 in complex with a Ste5 peptide

The structure was published by Bhattacharyya, R.P., Remenyi, A., Good, M.C., Bashor, C.J., Falick, A.M., and Lim, W.A., in 2006 in a paper entitled "The Ste5 scaffold allosterically modulates signaling output of the yeast mating pathway" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 2005.

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

This PDB entry contains a complex of 2 biomacromolecules, namely Mitogen-activated protein kinase FUS3 and STE5 peptide.

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.
