PDB entry 2dhb (supersedes 1dhb)

THREE DIMENSIONAL FOURIER SYNTHESIS OF HORSE DEOXYHAEMOGLOBIN AT 2.8 ANGSTROMS RESOLUTION

The structure was published by Bolton, W. and Perutz, M.F., in 1970 in a paper entitled "Three dimensional fourier synthesis of horse deoxyhaemoglobin at 2.8 Angstrom units resolution." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.8 Å and deposited in 1973.

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

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