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.
