NI BETA HEME HUMAN HEMOGLOBIN

The structure was published by Bruno, S., Bettati, S., Manfredini, M., et al., Tsuneshige, A., Yonetani, T., and Henry, E.R., in 2000 in a paper entitled "Oxygen binding by alpha(Fe2+)2beta(Ni2+)2 hemoglobin crystals." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.1 Å and deposited in 1999.

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 most likely forms heterotetramers.
