Apyrase and alpha-glucosidase in the salivary glands of Aedes albopictus.
An apyrase and an alpha-glucosidase were detected in the salivary glands extracts of adult Aedes albopictus. The apyrase is a 61,000 Da secreted protein that hydrolyses ATP and ADP. This protein is synthe-sized in adults and is preferentially accumulated in the distal lateral lobes of the female salivary glands. The alpha-glucosidase is a secreted 67,000 Da protein. This enzyme is synthesized during adult life and accumulated in the proximal-lateral lobes of both males and females. The results are discussed and compared with data previously obtained with Aedes aegypti salivary glands.
