Optimum environment. As with all enzymes, pectinases have an optimum temperature and pH at which they are most active. For example, a commercial pectinase might typically be activated at 45 to 55 Â°C and work well at a pH of 3.0 to 6.5. Pectinase is commonly used in fruit industries to speed up fruit juice extraction. Uses

For example, an enzyme often used in duplicating DNA comes from bacteria found at hot springs and the process is done at very high temperatures, as this is when the enzyme works best. However most enzymes of the human body have optimum temperatures at body temperature. If you have a graph of enzyme activity and temperature, it will be a curve rather than a sudden drop. This means that there will be a 'starting to denature' stage, gradually becoming more and more denatured as enzyme activity becomes more and more reduced.
