Crystal Structure of recombinant human Hexokinase type I with 2-deoxy-Glucose 6-Phosphate

The structure was published by Shen, L., Gao, Y., and Honzatko, R.B., in in a paper entitled "Inhibitor Sites of Unequal Affinity Linked by Binding Synergism in Mutant Forms of Recombinant Human Hexokinase Type-I" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.65 Å and deposited in 2012.

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