  Enzymatic Synthesis of Hydroquinoneβ-Xyloside from Xylooligosaccharides

  摘要：

  β-Xylosidase of Aspergillus pulverulentus catalyzes a transxylosylation reaction from xylooligosaccharides to acceptor hydroquinone. Two transfer products were purified and their structures were examined. These were identified as hydroquinone β-(1→4)-xyloside and hydroquinone 4-O-(β-xylosyl)-β-xyloside. The hydrolysis of these glycosides apparently took place accompanying the synthesis of the transfer products.
