Glucokinase in complex with an activator and glucose

The structure was published by Liu, S., Ammirati, M.J., Song, X., et al., Greasley, S.E., Pfefferkorn, J.A., and Qiu, X., in 2012 in a paper entitled "Insights into Mechanism of Glucokinase Activation: OBSERVATION OF MULTIPLE DISTINCT PROTEIN CONFORMATIONS." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.8 Å and deposited in 2012.

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

The PDB entry contains the structure of Glucokinase. This molecule has the UniProt identifier P35557 (HXK4_HUMAN)search. The sample contained 470 residues which is 98% of the natural sequence. Out of 470 residues 448 were observed and are deposited in the PDB.

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 is most likely monomeric.
