ANALYSIS OF THE CRYSTAL STRUCTURE, MOLECULAR MODELING AND INFRARED SPECTROSCOPY OF THE DISTAL BETA-HEME POCKET VALINE67(E11)-THREONINE MUTATION OF HEMOGLOBIN

The structure was published by Pechik, I., Ji, X., Fidelis, K., et al., Brinigar, W.S., Fronticelli, C., and Gilliland, G.L., in 1996 in a paper entitled "Crystallographic, molecular modeling, and biophysical characterization of the valine beta 67 (E11)-->threonine variant of hemoglobin." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.2 Å and deposited in 1995.

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

This PDB entry contains a complex of 2 biomacromolecules, namely HEMOGLOBIN (DEOXY) BETA-V67T.

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.
