Km, but not Vmax, values of XoxF proteins assayed with XoxG are Ln-dependent. (A) Representative Michaelis-Menten plots of La-XoxF (black), Ce-XoxF (red), and Nd-XoxF (blue), with 20 mM methanol as substrate and assayed in the presence of XoxG and horse heart cytochrome c. (B) Km of XoxF for XoxG versus ionic radius[29] of LnIII.
