Outline of Final Research Achievements

The X-ray structure of ketose 3-epimerase from Arthrobacter globiformis M30, which was previously reported to be a D-allulose 3-epimerase (AgDAE), was determined. AgDAE formed a homotetramer and its overall structure was more similar to that of L-ribulose 3-epimerase (L-RE) than to the known structures of D-psicose (alternative name D-allulose) 3-epimerases (D-PEs or D-AEs), although AgDAE and L-RE have different substrate specificities. Both AgDAE and L-RE have long helices in the C-terminal region that would contribute to the stability of the homotetramer. AgDAE showed higher enzymatic activity for L-ribulose than D-allulose; however, AgDAE is stable and is a unique useful enzyme for the production of D-allulose from D-fructose.

Academic Significance and Societal Importance of the Research Achievements

新規希少糖生産酵素として報告されたArthrobacter globiformis由来D-アルロース 3-エピメラーゼ(AgDAE)は、既報のD-アルロース 3-エピメラーゼ(D-AE)と類似構造を示したが、これまでに報告されていたL-リブロース3-エピメラーゼ(L-RE)とよりよく似ていた。各サブユニットのC末端側のα-ヘリックスが長く、四量体構造の安定化に寄与していた。AgDAE はL-リブロースに対して最大活性を示すこともわかったが、既報のL-REとは異なりD-アルロースに対する活性が高く、D-アルロース生産に有用なL-REファミリーに属するユニークな特性を示す酵素であることがわかった。
