Crystal structure of Thermococcus litoralis ADP-dependent glucokinase (GK)

Protein topology determines substrate-binding mechanism in homologous enzymes.

Crystal structure, SAXS and kinetic mechanism of hyperthermophilic ADP-dependent glucokinase from Thermococcus litoralis reveal a conserved mechanism for catalysis.
