HIGH-RESOLUTION X-RAY STUDY OF DEOXYHEMOGLOBIN ROTHSCHILD 37BETA TRP-> ARG: A MUTATION THAT CREATES AN INTERSUBUNIT CHLORIDE-BINDING SITE

The structure was published by Kavanaugh, J.S., Rogers, P.H., Case, D.A., and Arnone, A., in 1992 in a paper entitled "High-resolution X-ray study of deoxyhemoglobin Rothschild 37 beta Trp----Arg: a mutation that creates an intersubunit chloride-binding site." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 1992.

The experimental data on which the structure is based was also deposited.

This PDB entry contains a complex of 2 biomacromolecules, namely HEMOGLOBIN A (DEOXY) (ALPHA CHAIN) and HEMOGLOBIN A (DEOXY) (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.
