DEOXY RHB1.0 (RECOMBINANT HEMOGLOBIN)

The structure was published by Brucker, E.A., in 2000 in a paper entitled "Genetically crosslinked hemoglobin: a structural study." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.803 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 PROTEIN (DEOXYHEMOGLOBIN (ALPHA CHAIN)) and PROTEIN (DEOXYHEMOGLOBIN (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.
