Molecular Basis for Trehalase Inhibition Revealed by the Structure of Trehalase in Complex with Potent Inhibitors

Strong inhibitions: The inhibition of trehalases, enzymes which hydrolyze the disaccharide trehalose, is a target for novel antibiotic insecticides. The structures (see picture; C black, N blue, O red, S yellow) of a trehalase in complex with validoxylamine A (yellow) and 1-thiatetrazolin (blue) reveal that the inhibitors tightly bind to the enzyme through hydrogen bonds.
