Immobilization of d-allulose 3-epimerase into magnetic metal–organic framework nanoparticles for efficient biocatalysis [PDF]

World Journal of Microbiology and Biotechnology, 2021
Abstract D-allulose is a rare low-calorie sugar that has many fundamental biological functions. D-allulose 3-epimerase from Agrobacterium tumefaciens (AT-DAEase) catalyzes the conversion of D-fructose to D-allulose. The enzyme has attracted considerable attention because of its mild catalytic properties.

Reaction Engineering and Comparison of Electroenzymatic and Enzymatic ATP Regeneration Systems

ChemElectroChem, Volume 10, Issue 22, November 14, 2023., 2023
An electrochemically coupled ATP regeneration by pyruvate oxidase and acetate kinase for the phosphorylation of mevalonate was established and expanded by a polyphosphate kinase. The reaction was characterized and compared with other ATP regenerating systems in terms of the phosphate donor properties and biocatalytic metrics.
