My protein is phosphofructokinase :it is the enzyme that phosphorylates fructose-6-phosphate in glycolysis and other metabolic pathways or the enzyme using fructose 1-phosphate in the same reaction .Its code number is 1pfk .It has 320 residues ,sequence A.B ,26 helix .THIS CRYSTAL STRUCTURE REPRESENTS THE ACTIVE (R-STATE) 1PFK .CONFORMATION OF E. COLI PFK. THE CRYSTALS WERE GROWN WITH FRUCTOSE-6-PHOSPHATE AND ADP/MG++, BUT A SUBSTANTIAL PROPORTION OF THE REACTION PRODUCT FRUCTOSE-1,6-BISPHOSPHATE IS OBSERVED IN THE STRUCTURE. THE 1-PHOSPHATE GROUP HAS BEEN ASSIGNED AN OCCUPANCY OF 0.5 IN THIS ENTRY BUT THIS IS VERY APPROXIMATE.
