title: Fitting enzyme-kinetic data to V/K.
abstract: Kinetic data from enzyme-catalyzed reactions have been analyzed traditionally in terms of the Michaelis-Menten equation, which assumes that the maximal velocity (V) and the Michaelis constant (K) are the primary kinetic constants. But what is needed from most kinetic studies today is V/K. A new form of the equation is proposed which assumes that V and V/K are the primary kinetic constants: v = (V . S . V/K)/(V + S . V/K). Computer fittings of both experimental and simulated velocity data to both equations give results favoring the new equation.
