Sequence- and Structure-Based Mining of Thermostable D‑Allulose 3‑Epimerase and Computer-Guided Protein Engineering To Improve Enzyme Activity

D-Allulose, a functional sweetener, can be synthesized from fructose using D-allulose 3-epimerase (DAEase). Nevertheless, a majority of the reported DAEases have inadequate stability under harsh industrial reaction conditions, which greatly limits their ...

Construction of the Thermostable D-Allulose 3-Epimerase from Arthrobacter globiformis M30 by Protein Engineering Method.

Journal of applied glycoscience
D-Allulose 3-epimerase catalyzes C-3 epimerization between D-fructose and D-allulose was found in Arthrobacter globiformis strain M30. The enzyme gene was cloned, and its recombinant enzyme and the mutant variants were expressed in E. coli. Using the information of the sequence and model structure, we succeed in the improvement of melting temperature ...

Characterisation of Streptomyces spheroides NovW and revision of its functional assignment to a dTDP-6-deoxy-D-xylo-4-hexulose 3-epimerase

, 2006
Characterisation of recombinant Streptomyces spheroides NovW in vitro suggests that it is not a kinetically competent dual action dTDP-6-deoxy-d-xylo-4-hexulose 3,5-epimerase, but possesses only significant 3-epimerase ...
