ID	Method	pH	Temperature	Details
1				THE CRYSTALS USED IN THIS STUDY WERE GROWN FROM POTASSIUM PHOSPHATE WITH 2 MILLIMOLAR FRUCTOSE-6-PHOSPHATE. FOR THIS LIGANDED STRUCTURE, THE CRYSTALS WERE SOAKED IN FRUCTOSE-6-PHOSPHATE (F6P) AND ADP/MG IN POTASSIUM TARTRATE. F6P 323 AND THE EFFECTOR SITE ADP 326 ARE TREATED AS FULLY OCCUPIED WHILE ADP 324 IS TREATED AS HALF OCCUPIED.
