1.25A resolution crystal structure of human hemoglobin in the carbonmonoxy form

The structure was published by Park, S.-Y., Yokoyama, T., Shibayama, N., Shiro, Y., and Tame, J.R., in 2006 in a paper entitled "1.25 a resolution crystal structures of human haemoglobin in the oxy, deoxy and carbonmonoxy forms." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.25 Å and deposited in 2006.

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

This PDB entry contains a complex of 2 biomacromolecules, namely Hemoglobin alpha subunit and Hemoglobin beta subunit.

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.
