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.

== Function ==
 +
[https://www.uniprot.org/uniprot/XYNA_STRLI XYNA_STRLI] Contributes to hydrolyze hemicellulose, the major component of plant cell-walls. XLNA and XLNB seem to act sequentially on the substrate to yield xylobiose and xylose as carbon sources.
