General description

Trehalase is a glycosidase[1] that occurs in many forms and is found in all tissues.[2] It belongs to the glycoside hydrolase 37 (GH37) family of the carbohydrate-active enzyme (CAZy) classification.[1][3]
Trehalose is the main haemolymph sugar in most insects and is potentially a prime target for an invading pathogenic fungus.

Application

Trehalase has been used:
  • in a study to assess changes in carbohydrate metabolism in Plasmopara viticola-infected grapevine leaves[4]
  • in a study to investigate growth arrest by trehalose-6-phosphate
  • to quantify the intracellular trehalose in Lactobacillus casei cells[5]

Biochem/physiol Actions

Trehalase catalyzes the hydrolysis of trehalose to produce two glucose units. It mediates flight metabolism, molting induced chitin production and tolerance towards cold temperature.[2]

Physical form

Solution in 50% glycerol containing 1% Triton™ X-100 and 25 mM potassium phosphate, pH 6.5

Other Notes

One unit will convert 1.0 μmole of trehalose to 2.0 μmoles of glucose per min at pH 5.7 at 37 °C (liberated glucose determined at pH 7.5).
