Crystal structure of oxidized alpha hemoglobin bound to AHSP

The structure was published by Feng, L., Zhou, S., Gu, L., et al., Weiss, M.J., Gow, A.J., and Shi, Y., in 2005 in a paper entitled "Structure of oxidized alpha-haemoglobin bound to AHSP reveals a protective mechanism for haem." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.4 Å and deposited in 2005.

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

This PDB entry contains a complex of 2 biomacromolecules, namely Alpha-hemoglobin stabilizing protein and Hemoglobin alpha 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.
