Nettet1. jan. 1982 · Studies of the effects of pH on the stability of soil enzymes are important because exposure to extreme pH values may irreversibly inactivate enzymes that play an essential role in nutrient (N, C, P and S) transformations and humus formation. The hydrogen ion concentration of soils can vary considerably; most soils range between pH 4. NettetAny change in pH affects the protein structure and a decline in enzyme activity beyond the optimum pH could be due to enzyme inactivation or its instability. It could be concluded from the results that tannase from the new isolate needed an acidic protein environment to be active, fungal tannase is an acidic protein in general ( Mahapatra et al. 2005 ).

NettetEnzymes work best within a certain pH range, and, as with temperature, extreme pH values (acidic or basic) can make enzymes denature. Induced fit The matching between an enzyme's active site and the substrate isn’t just like two puzzle pieces fitting together (though scientists once thought it was, in an old model called the “lock-and-key” model).

NettetChange in pH: - Most enzymes have their own pH which they work best at, their optimum pH. This usually depends on the area of the body on the environment that the enzyme usually occurs in.
