The study describes enzymes from a human gut microbiome that break glycosidic linkages of α and β stereochemistry, including bonds not typically cleaved by standard glycosidases like thioglycosides and pseudoglycosidic bonds.
These enzymes exhibit a unique hydrolytic mechanism involving oxidation/reduction and elimination/hydration steps, catalyzed by interchangeable enzyme modules, found in Gram-positive and Gram-negative bacteria, in diverse environments beyond the gut microbiome.
