Crystal Structure of deoxy HbalphaYQ, a mutant of HbA

The structure was published by Miele, A.E., Draghi, F., Arcovito, A., et al., Brunori, M., Travaglini-Allocatelli, C., and Vallone, B., in 2001 in a paper entitled "Control of heme reactivity by diffusion: structural basis and functional characterization in hemoglobin mutants." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.2 Å and deposited in 2001.

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.
