WebEnzyme stock solutions were diluted in 100 mM sodium phosphate buffer, to 12.8 μM pepsin, at pH 2 and to 2.5 μM trypsin, at pH 8. 925 μl of the enzyme dilutions were incubated in Eppendorf tubes at 37 °C for 30 min, at 300 rpm in a Thermomixer (Eppendorf AG, Germany). At four time intervals of 2000 s, 20 μl of substrate solution was added. WebFor example, the activity of trypsin is known to be optimal at a pH of around 8.0. If the pH of the solution is increased or decreased from this optimal value, the activity of the enzyme will decrease. This is because the ionization state of the amino acid residues in the enzyme can change at different pH values, which can alter the enzyme's ...
