"From the elemental analysis, [investigators] could only estimate the total concentration of phosphorus, which was ~300 mM. A substantial part of this is present in bound phosphate groups or in the form of polyphosphates. To estimate the free cytosolic phosphate concentration, [investigators] used values from the literature. A broad range was found, from 10 to 75 mM [primary sources]. As the growth conditions applied by Wu et al. [primary source 14] were almost identical to [their] growth conditions, [they] used their value of 50 mM. However, [they] note that varying the phosphate concentration between 10 and 75 mM did not affect the reported Vmax values (Fig. S1), as reported below." |
