Table 4.

Kinetic constants of ACE-catalyzed reactions at different peptide concentrations.

Catalytic parameters Control H5 H6
Concentration (mg/ml) 0 0.05 0.1 0.05 0.1
Vm (ΔA/min) 0.191 0.120 0.070 0.099 0.049
Km (mg) 3.199 3.948 6.552 6.308 8.054
CE 0.060 0.030 0.011 0.016 0.006

Km is the Michaelis constant, Vmax is maximum reaction velocity, CE is the catalytic efficiency (Vmax/Km).
