HIGH RESOLUTION CRYSTAL STRUCTURE OF DEOXY HEMOGLOBIN COMPLEXED WITH A POTENT ALLOSTERIC EFFECTOR

The structure was published by Safo, M.K., Moure, C.M., Burnett, J.C., Joshi, G.S., and Abraham, D.J., in 2001 in a paper entitled "High-resolution crystal structure of deoxy hemoglobin complexed with a potent allosteric effector." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.85 Å and deposited in 2000.

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

This PDB entry contains a complex of 2 biomacromolecules, namely HEMOGLOBIN ALPHA CHAIN and HEMOGLOBIN BETA CHAIN.

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 heterotetramers.
