A subset of Arabidopsis FRKs shares biochemical cofactor requirements. Scatterplots comparing enzyme activity of FRK1 (blue), FRK2 (red), and FRK3 (green) in various conditions normalized to that of their respective control experiment. Control experiments were carried out in a complete mixture as compared to mixtures where inorganic phosphate was omitted (−Pi), K+ was replaced with Na + to preserve ionic strength (−K+), Mg2+ was omitted and replaced with EDTA (EDTA), or ATP was replaced with either GTP (GTP) or (UTP). Statistical analysis was conducted with Dunnett’s post hoc test to compare the mean of each enzyme in each condition to the mean of the control experiment for the corresponding enzyme. *p < 0.05, ****p < 0.0001, ns = not significant. Experiments were carried out in quadruplicate, all data points are shown
