A Inhibition of polyphosphate on enzyme activity. The blue, green and red lines represent the effects of polyP6 on LhPPK, SlPPK, and AtAdk activity. B The utilization of polyP6 by different PPKs. The black bar is the amount of ATP produced by the reaction of different PPKs with 1 mM polyP6 and 10 mM ADP as substrates. The gray bar is the amount of ATP produced by the reaction of different PPKs with 10 mM ADP as the substrate. All measurements were carried out in triplicates
