Summary

Trehalase from the salivary glands and the midgut ofSesamia inferens showed optimum activity at pH 5.8, and at temperatures of 50 and 60°C respectively. The increase in the incubation period, enzyme concentration, and substrate concentration respectively increased the end-product, the hydrolysis, and the rate of hydrolysis of the substrate. Dialysis did not affect, tryptophan accelerated, and other amino acids and end-product inhibited the enzyme activity.
