Ping pong mechanism derivation

WebThe derivation of equilibrium rate equations by the conventional method amounts to solving as many simultaneous linear equations as the number of enzyme species, and the algebraic manipulation can be very cumbersome when there are many enzyme species. WebThe computer algebra system Wolfram Mathematica v. 12.2 (Champaign, IL, USA) was used to program scripts to numerically and analytically solve the ODE systems of the irreversible uni–uni Michaelis–Menten and ping-pong reaction mechanisms, in which the enzyme followed a one-step suicide substrate inactivation. The Runge–Kutta method was ...
