3 Enzyme Activity:
kenz

Enzyme Molecule:
PIP2-Ca-PLA2*

AA
  10 x raise oct 22 12 x and rescale for k2 = 4 * k3 convention oct 24 Increase further to get the match to expt, which was spoilt due to large accumulation of PLA2 in the enzyme complexed forms. Lets raise k3, leaving the others at k1 = 1.5e-5 and k2 = 144 since they are large already.
4 Enzyme Activity:
kenz

Enzyme Molecule:
DAG-Ca-PLA2*

  10 X raise oct 22 12 X raise oct 24 + conversion to k2 =4 * k3
5 Enzyme Activity:
kenz

Enzyme Molecule:
PLA2*-Ca
201204explicit E-S complexAPC
AA
  This form should be 3 to 6 times as fast as the Ca-only form. I have scaled by 4x which seems to give a 5x rise. 10x raise Oct 22 12 x oct 24, changed k2 = 4 * k3
