1 Enzyme Activity:
k27

Enzyme Molecule:
mass
1024explicit E-S complexHeaviside_dup
GM
  Equation 17 dGM/dt = k27 * mass * Heaviside_out. k27 = 0.2 If k3 << k2, we have ES ~ E.S.k1/k2 and rate = k3 * ES. So we assume k2 = 1, k3 = 0.1, then k1 = 10 * k27 so k1 = 2. This gives a rather low Km, leading to much complex formation. Let us use MM form, and assume Km >> Heaviside_out. Take Km = 10, then kcat = Km * k27 = 2
2 Enzyme Activity:
mu

Enzyme Molecule:
GM
1.000010.1224explicit E-S complexAminoAcids
mass
  Rate = E.S.kcat/(Km + S) We want to represent dmass/dt = epsilon.mu.GM. Epsilon is 1 for now. mu = 0.061 S here is AA, buffered to 1. We assign Km = 1 for simplicity. Then kcat = 2 * mu = 0.122
