WebNon-competitive inhibition is a type of enzyme inhibition where the inhibitor reduces the activity of the enzyme and binds equally well to the enzyme whether or not it has already bound the substrate. [1] [2] This is unlike allosteric inhibition, where binding affinity for the substrate in the enzyme is decreased in the presence of an inhibitor. WebFrom the equations and graphs describing the three modes of enzyme inhibition (Figures 2.6 and 2.7), it can be seen that competitive ... No irreversible inhibition was observed.
