DEOXY HUMAN HEMOGLOBIN

The structure was published by Tame, J.R. and Vallone, B., in 2000 in a paper entitled "The structures of deoxy human haemoglobin and the mutant Hb Tyralpha42His at 120 K." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.8 Å and deposited in 1998.

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.
