Fig. 2From: In vitro biosynthesis of ATP from adenosine and polyphosphateRelative activities of six PPKs. The highest enzyme activity of all PPKs was set as 100% of relative activity. At 37 °C and pH 8.0 (the optimal reaction conditions for AtAdk), the enzymatic activities of PPK2-I to ADP and the enzymatic activities of PPK2-III to AMP were determined. All measurements were carried out in triplicatesBack to article page
