What is competitive Inhibition?
In competitive inhibition, the substrate and inhibitor cannot bind to the enzyme at the same time, as shown in the figure on the right. This usually results from the inhibitor having an affinity for the active site of an enzyme where the substrate also binds; the substrate and inhibitor compete for access to the enzyme's active site. This type of inhibition can be overcome by sufficiently high concentrations of substrate (Vmax remains constant), i.e., by out-competing the inhibitor. However, the apparent Km will increase as it takes a higher concentration of the substrate to reach the Km point, or half the Vmax. Competitive inhibitors are often similar in structure to the real substrate.
How to Calculate Michaelis Constant given Modifying Factor in Michaelis Menten Equation?
Michaelis Constant given Modifying Factor in Michaelis Menten Equation calculator uses Michaelis Constant = (Substrate Concentration*((1/Enzyme Substrate Modifying Factor)*Maximum Rate)-Initial Reaction Rate)/((Enzyme Modifying Factor/Enzyme Substrate Modifying Factor)*Substrate Concentration) to calculate the Michaelis Constant, The Michaelis constant given modifying factor in Michaelis Menten equation formula is defined as the enzyme activity under various substrate and inhibitor concentrations, to obtain a modified Michaelis–Menten equation. Michaelis Constant is denoted by KM symbol.
