Amino-acids Amines and CO2             V. Coagulation enzymes Pectase Coagulates pectic bodies ........

In such cases, the parasite secretes both a pectose-dissolving enzyme, known as "pectase" and a "cellulase" which attacks the cell-wall material in order to provide for the entry of the fungus into the cells.

As the fruit ripens the pectase acts upon the pectose, which is insoluble in water, converting it into pectin, which is soluble.

Pectose and pectase always exist in the unripe fruit.

Green fruit contains two substances, called "pectase" and "pectose" and, by the action of the sun in ripening, these substances change into pectin which makes fruit jelly.
