Figure 3.
Effects of divalent metal ions on SM hydrolysis. The values of V[max] and K[m] of hydrolytic activity for the dispersed SM were measured using [N-methyl-^14C]SM. The measured result and the ionic radius of each divalent cation are plotted against the average Lewis acid strength (37). The plots with squares, diamonds, and triangles are the plots of K[m], V[max], and the ionic radius of each divalent cation.
