DEOXY HEMOGLOBIN (90% RELATIVE HUMIDITY)

The structure was published by Biswal, B.K. and Vijayan, M., in 2002 in a paper entitled "Structures of human oxy- and deoxyhaemoglobin at different levels of humidity: variability in the T state." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.7 Å and deposited in 2002.

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