Enzymatic kinetics. (A) Data from Figure 5D (points) were replotted using molar concentration and fitted by Equation 1 (curve). (B) Lineweaver-Burk plot of reciprocal initial rate of substrate reduction versus reciprocal substrate concentration. The data (points) were fitted by a straight line. The best-fit parameters are indicated. The goodness of fit is indicated by R² (B) or adjusted R² (A).
