Membrane-bound sucrose hydrolase contributes to carbohydrate metabolism in Bombyx mori.

Insects mainly rely on sucrase to hydrolyze sucrose into glucose and fructose, supplying carbon and energy for growth and development. Although soluble and membrane-associated sucrases have been identified in several insects, the physiological function of the membrane-bound sucrase remains unclear. Here, we performed a comprehensive analysis of the biochemical properties and physiological functions of the membrane-bound sucrase (BmSUH) in Bombyx mori.
