General description

Trehalase is a glycosidase that occurs in many forms and is found in all tissues. It belongs to the glycoside hydrolase 37 (GH37) family of the carbohydrate-active enzyme (CAZy) classification.
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
  • in a study to investigate growth arrest by trehalose-6-phosphate
  • to quantify the intracellular trehalose in Lactobacillus casei cells

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.

Unit Definition

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).

Physical form

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

Although trehalose has recently gained interest because of its pharmaceutical potential, its clinical use is hampered due to its low bioavailability. Hence, hydrolysis-resistant trehalose analogues retaining biological activity could be of interest. In this study, 34 4- and 6-O-substituted trehalose

Glycolysis is a metabolic pathway that is central to the assimilation of carbon for either respiration or fermentation and therefore is critical for the growth of all organisms. Consequently, glycolytic transcriptional regulation is important for the metabolic flexibility of pathogens
