Equation (11). the Michaelis-Menten equation. describes the kinetic behavior of an enzyme that acts according to the simple model (1). Equation (11) is of the form . y = ax/ (b + x) (does this look familiar? ) This is the equation of a rectangular hyperbola. just like the saturation equation …
The Michaelis–Menten equation (Eqn (4) ) is the rate equation for a one-substrate enzyme-catalyzed reaction. 38 This equation relates the initial reaction rate (v0). the maximum reaction rate (Vmax). and the initial substrate concentration [S] through the Michaelis …
The Michaelis-Menten equation can be expressed as: The velocity is therefore proportional to the enzyme concentration. not inversely so. is also referred to as the turnover number. As the substrate concentration keeps increasing. then we end up with a steady state in which all the enzyme is bound.
Several simplifying assumptions allow for the derivation of the Michaelis-Menten equation: (1) E+S ESThe binding step () is fast. allowing the reaction to quickly reach equilibrium ratios of [E]. [S]. and [ES]. The catalytic step () is slower. and thus rate-limiting.
Equation (11). the Michaelis-Menten equation. describes the kinetic behavior of an enzyme that acts according to the simple model (1). Equation (11) is of the form y = ax/ (b + x) (does this look familiar? ) This is the equation of a rectangular hyperbola. just like the saturation equation for the binding of dioxygen to myoglobin.
The Michaelis-Menten model (1) is the one of the simplest and best-known approaches to enzyme kinetics. It takes the form of an equation relating reaction velocity to substrate concentration for a system where a substrate Sbinds reversibly to an enzyme Eto
