Structure of deoxy-quaternary haemoglobin with liganded beta subunits

The structure was published by Luisi, B., Liddington, B., Fermi, G., and Shibayama, N., in 1990 in a paper entitled "Structure of deoxy-quaternary haemoglobin with liganded beta subunits." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.6 Å and deposited in 1990.

The experimental data on which the structure is based was not deposited.

This PDB entry contains a complex of 2 biomacromolecules, namely HEMOGLOBIN (NICKELOUS DEOXY) (ALPHA CHAIN) and HEMOGLOBIN (FERROUS CARBONMONOXY) (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.
