Direct observation of photolysis-induced tertiary structural changes in human haemoglobin; Crystal structure of alpha(Ni)-beta(Fe) hemoglobin (laser photolysed)

The structure was published by Adachi, S., Park, S.-Y., Tame, J.R.H., Shiro, Y., and Shibayama, N., in 2003 in a paper entitled "Direct observation of photolysis-induced tertiary structural changes in hemoglobin" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.45 Å and deposited in 2003.

The experimental data on which the structure is based was not 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 has more than one probable quaternary state observed. For more details see the quaternary structure page.
