Enterobacter hafniae and Aeromonas hydrophila ADPglucose synthetases were purified approximately 39-and 61-fold, respectively, over the crude extract. Both enzymes were heat stable at 60°C in the presence of inorganic phosphate. The molecular weights of both enzymes were approximately 200,000 which are similar to other enteric ADPglucose synthetases(More)
