title: Enzymatic synthesis of hydroquinone beta-xyloside from xylooligosaccharides.
abstract: beta-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 beta-(1-->4)-xyloside and hydroquinone 4-O-(beta-xylosyl)-beta-xyloside. The hydrolysis of these glycosides apparently took place accompanying the synthesis of the transfer products.
