Novel endo-arabinanase having arabinobiose hydrolysis activity and uses thereof

摘要

The present invention relates to a novel endo-arabinase (AN-A _X ) having hydrolytic activity of arabinobios and a use thereof. When the AN-A _X enzyme of the present invention is used, exo-type AF (α- L-arabinofuranosidase)High-efficiency L-arabinose production is possible from straight-chain _{arabinan or arabino oligosaccharide without enzymes. When the AN-A X} enzyme of the present invention and the exo-type AF enzyme are simultaneously treated, the exo-type AF enzyme and Compared to the case of simultaneous treatment of the existing endo-type AN enzyme, it is possible to greatly shorten the enzyme reaction time in the industrial L-arabinose production process, thereby increasing productivity and economic efficiency.
