WebInhibition and activation of enzymes via other molecules are important ways that enzymes are regulated. Inhibitors can act competitively or noncompetitively; noncompetitive inhibitors are usually allosteric ( allo (other) steric (form). Activators can also enhance the function of enzymes allosterically. WebMar 6, 2024 · It is typically done as follows. First, one performs a set of V0 vs. [S] reactions without inhibitor (20 or so tubes, with buffer and constant amounts of enzyme, varying amounts of substrate, equal reaction times). V0 vs. [S] is plotted (Figure 4.35 red line), as well as 1/V0 vs. 1/ [S] (Figure 4.36 green line).
