Michaelis-Menten equation

[‚mik·ä¦ā·ləs ′men·tən i‚kwā·zhən]
(biochemistry)
A mathematical equation expressing the hyperbolic relationship between the initial velocity, Vo , and the substrate concentration, [S ], in a number of enzyme-catalyzed reactions such that Vo = Vmax[S ]/ Km + [S ], where Vmaxis the maximum velocity and Km is the Michaelis constant.
