Fig. 3From: Characterization of a hyperthermophilic phosphatase from Archaeoglobus fulgidus and its application in in vitro synthetic enzymatic biosystemEffects of cations on the specific activity of AfPase. The reactions were performed in 100 mM HEPES buffer (pH 7.0) containing 1 mM p-nitrophenyl phosphate, 5 mM different ions, and appropriate concentration of phosphatase at 85 °CBack to article page
