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 Modifying Factor of Enzyme Substrate Complex?
Modifying Factor of Enzyme Substrate Complex calculator uses Enzyme Substrate Modifying Factor = 1+(Inhibitor Concentration/Enzyme Substrate Dissociation Constant) to calculate the Enzyme Substrate Modifying Factor, The Modifying factor of enzyme substrate complex formula is defined as the relation with inhibitor concentration and with the enzyme-substrate dissociation constant. Enzyme Substrate Modifying Factor is denoted by α' symbol.
