In enzymology, an alpha,alpha-trehalase (EC 3.2.1.28) is an enzyme with system name alpha,alpha-trehalose glucohydrolase. This enzyme catalyzes the chemical reaction
alpha,alpha-trehalose + H2OThus, the two substrates of this enzyme are alpha,alpha-trehalose and H2O, whereas its product is D-glucose.
This enzyme belongs to the family of hydrolases, specifically those glycosidases that hydrolyse O- and S-glycosyl compounds. The systematic name of this enzyme class is alpha,alpha-trehalose glucohydrolase. This enzyme is also called trehalase. This enzyme participates in starch and sucrose metabolism.
Structural studies
As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes 2JF4 and 2JG0.
