Fig. 6

Effect of protonation on the two steps of the sequential mechanism. Energy barriers a ΔE 1 ǂ for breaking the Pγ-Oβγ bond and b ΔE 2 ǂ for breaking of water Wa (as given in Table 2). Greek letters (α,β,γ) indicate on which phosphate the proton is located (for example αγ means αγ-protonation). Zero means that there are no protons on the triphosphate (nP = 0)
