HEMOGLOBIN (VAL BETA1 MET, TRP BETA37 TYR) MUTANT

The structure was published by Kavanaugh, J.S., Weydert, J.A., Rogers, P.H., and Arnone, A., in 1998 in a paper entitled "High-resolution crystal structures of human hemoglobin with mutations at tryptophan 37beta: structural basis for a high-affinity T-state,." (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 also deposited.

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