Crystal structure of phosphoglucose/phosphomannose isomerase from Pyrobaculum aerophilum in complex with fructose 6-phosphate

The structure was published by Swan, M.K., Hansen, T., Schoenheit, P., and Davies, C., in 2004 in a paper entitled "Structural basis for phosphomannose isomerase activity in phosphoglucose isomerase from Pyrobaculum aerophilum: a subtle difference between distantly related enzymes." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.5 Å and deposited in 2004.

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

This PDB entry contains multiple copies of the structure of glucose-6-phosphate isomerase.

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 homodimers.
