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 Inhibitor Concentration given Apparent Michaelis Menten Constant?
Inhibitor Concentration given Apparent Michaelis Menten Constant calculator uses Inhibitor Concentration = ((Apparent Michaelis Constant/Michaelis Constant)-1)*Enzyme Inhibitor Dissociation Constant to calculate the Inhibitor Concentration, The Inhibitor concentration given apparent Michaelis Menten constant formula is defined as the relation with Michaelis constant and apparent value of Michaelis constant and with inhibitor's dissociation constant. Inhibitor Concentration is denoted by I symbol.
