During copy editing, an error was introduced in a column label in Table 1. The label of the last column should be kcat/Km. This error has now been corrected and does not affect the results and conclusions of this work.

a Values taken from Collard et al., 2016 (20).
b Vmax was calculated using kcat values from Collard et al., 2016 (20). Molecular mass values of 34,540.68 Da and 34,624.58 Da for murine PGP and Pho13, respectively, were used in the calculation.
