REFINEMENT OF A PARTIALLY OXYGENATED T STATE HAEMOGLOBIN AT 1.5 ANGSTROMS RESOLUTION

The structure was published by Waller, D.A. and Liddington, R.C., in 1990 in a paper entitled "Refinement of a partially oxygenated T state human haemoglobin at 1.5 A resolution." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.5 Å and deposited in 1990.

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

This PDB entry contains a complex of 2 biomacromolecules, namely HEMOGLOBIN A (OXY) (ALPHA CHAIN) and HEMOGLOBIN A (DEOXY) (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.
