Crystals structure of Human Glucokinase in complex with small molecule activator

A publication describing this structure is not available. The depositing authors are Ogg, D.J.search; Hargreaves, D.search; Gerhardt, S.search; Flavell, L.search; McAlister, M.search

This crystal structure was determined using X-ray diffraction at a resolution of 2.1 Å and deposited in 2013.

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

The PDB entry contains the structure of Glucokinase isoform 3. This molecule has the UniProt identifier P35557 (HXK4_HUMAN)search. The sample contained 456 residues which is 97% of the natural sequence. Out of 456 residues 443 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.
