Initial velocities of reactions catalyzed by XOD and PNPase. (A) Oxidation of guanine by XOD as a function of substrate concentration. The continuous line represents the best fit to the Michaelis-Menten equation. (B) Phosphorolysis of deoxyguanosine by PNPase as a function of substrate concentration. The continuous line represents the best fit to the Michaelis-Menten equation.
