An α,α-trehalase (EC 3.2.1.28) is an enzyme with systematic name "α,α-trehalose glucohydrolase". This enzyme catalyzes the chemical reaction
α,α-trehalose + H2O formula_1 2 -glucose
This enzyme belongs to the family of hydrolases, specifically those glycosidases that hydrolyse O- and S-glycosyl compounds. It is also called trehalase, and it 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.
