Crystal structure of E.coli glucokinase (Glk)

The structure was published by Lunin, V.V., Li, Y., Schrag, J.D., Iannuzzi, P., Cygler, M., and Matte, A., in 2004 in a paper entitled "Crystal structures of Escherichia coli ATP-dependent glucokinase and its complex with glucose." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.36 Å and deposited in 2003.

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

This PDB entry contains multiple copies of the structure of Glucokinase.
