  • PubMed Abstract: 

    The atomic resolution structures of xylobiose-derived isofagomine and xylobiose-derived deoxynojirimycin in complex with the xylanase Xyn10A from Streptomyces lividans reveal undistorted (4)C(1) chair conformed sugars and, in the case of the deoxynojirimycin analogue, suggest unusual pK(a) changes of the enzyme's catalytic machinery upon binding.
