Substrate specificities
GH37 enzymes have been shown, to date, to hydrolyse only the disaccharide trehalose (α-D-glucopyranosyl-(1→1)-α-D-glucopyranoside) into two glucose units (EC 3.2.1.28).
Kinetics and Mechanism
Content is to be added here.
Catalytic Residues
Content is to be added here.
Three-dimensional structures
The only structural representative from GH37 to date is the trehalase from Escherichia coli, which was solved using X-ray crystallography [1]. The structure revealed a (α/α)6 barrel fold, and was placed into clan GH-G. Structures have been solved with the inhibitors validoxylamine A, 1-thiatrehazolin and a casuarine analogue [1, 2].
