The structure has not been published. The depositing authors are Brucker, E.A.search

This crystal structure was determined using X-ray diffraction at a resolution of 1.8 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 most likely forms heterotetramers.
