STRUCTURE OF INSULIN. RESULTS OF JOINT NEUTRON AND X-RAY REFINEMENT

The structure was published by Wlodawer, A., Savage, H., and Dodson, G., in 1989 in a paper entitled "Structure of insulin: results of joint neutron and X-ray refinement." (abstract).

The structure was determined using a combination of experimental techniques (X-ray diffraction and Neutron diffraction) at a resolution of 1.5 Å and deposited in 1988.

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

This PDB entry contains a complex of 2 biomacromolecules, namely INSULIN (CHAIN A) and INSULIN (CHAIN B).

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 has more than one probable quaternary state observed. For more details see the quaternary structure page.
