TWO ADDITIONAL DENSITY REGIONS IN THE ACTIVE CENTER WERE FITTED BY A 1:1 MIXTURE OF DIHYDROXYACETONE AND PHOSPHATE AND A 1:1 MIXTURE OF PHOSPHATE AND FIVE WATER MOLECULES, RESPECTIVELY. DIHYDROXYACETONE WAS AN 0.2% (V/V) IMPURITY IN THE AUTOCLAVED CRYO PROTECTANT GLYCEROL. THE PHOSPHATE WAS FROM THE LAST PURIFICATION BUFFER AND HAD ESCAPED DIALYSIS.
