(A) Influence of nine fixed concentrations of Lys2-Tat(1–9) (1 × 10−5 m to 3 … NettetHere, we demonstrate that amino acid substitutions at different positions of Tat(1–9) can result in a change of the inhibition type. Certain Tat(1–9)-related peptides are found to be competitive, and others linear mixed-type or parabolic mixed-type inhibitors indicating different inhibitor binding sites on DP IV, at the active site and out of the active site.

Dixon plot and slope replot of a linear mixed-type inhibition ...

Mixed inhibition is a type of enzyme inhibition in which the inhibitor may bind to the enzyme whether or not the enzyme has already bound the substrate but has a greater affinity for one state or the other. It is called "mixed" because it can be seen as a conceptual "mixture" of competitive inhibition, in which the inhibitor can only bind the enzyme if the substrate has not already bound, and uncomp… NettetV_ {max} V max is the Y-value (initial rate of reaction value) at which the graph above plateaus.
