Pectinesterases.—The pectinesterase activities in tomatoes stored at different temperatures have been determined. The level of activity is low in mature green fruit but increased rapidly at ca. 20 °C - but not at either 4 or 33 C. The storage-life of tomatoes kept at 33 °C for several days is increased, owing to suppression of the polygalacturonase activity. Multiple forms of the enzyme are responsible for the pectinesterase activity of tomatoes one of the forms has been characterized. ...
