Abstract excerpt

The β-xylosidase B from Bifidobacterium adolescentis ATCC15703 belongs to the newly characterized family 120 of glycoside hydrolases. In order to investigate its catalytic mechanism, an extensive kinetic study of the wild-type enzyme and mutants targeting the three highly conserved residues Asp(393), Glu(416) and Glu(364) was performed. NMR analysis of the xyloside hydrolysis products, the change of the reaction...
