T STATE HUMAN HEMOGLOBIN [ALPHA V96W], ALPHA AQUOMET, BETA DEOXY

The structure was published by Puius, Y.A., Zou, M., Ho, N.T., Ho, C., and Almo, S.C., in 1998 in a paper entitled "Novel water-mediated hydrogen bonds as the structural basis for the low oxygen affinity of the blood substitute candidate rHb(alpha 96Val-->Trp)." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 1997.

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

This PDB entry contains a complex of 2 biomacromolecules, namely HEMOGLOBIN.

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.
