2hbe Summary



The structure was published by Johnson, K.A., in 1993 in a paper entitled "High Resolution X-Ray Structures of Myoglobin-and Hemoglobin-Alkyl Isocyanide Complexes" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 1994.

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

This PDB entry contains a complex of 2 biomacromolecules, namely HEMOGLOBIN A (N-BUTYL ISOCYANIDE) (ALPHA CHAIN) and HEMOGLOBIN A (N-BUTYL ISOCYANIDE) (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.
