DEOXY RHB1.1 (RECOMBINANT HEMOGLOBIN)

The structure was published by Kroeger, K.S. and Kundrot, C.E., in 1997 in a paper entitled "Structures of a hemoglobin-based blood substitute: insights into the function of allosteric proteins." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 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-BASED BLOOD SUBSTITUTE.

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 heterotrimers.
