A nanoplatelet serves as a substrate for immobilizing enzymes involved in consecutive reactions as a cascade. This results in a significant increase in the rate of catalysis as well as final product yield compared to non-immobilized enzymes or enzymes immobilized to quantum dots.

Provided herein, in some embodiments, are systems, methods, and compositions (e.g., cells and cell lysates) for enzymatically converting a polymeric glucose carbohydrate (e.g., starch) to sugar.

Disclosed herein are methods of producing hexoses from saccharides by enzymatic processes. The methods utilize fructose 6-phosphate and at least one enzymatic step to convert it to a hexose.

The invention relates to immobilized enzyme compositions for the preparation of a hexose. Hexoses include, for example, tagatose, psicose, fructose, allose, mannose, galactose, altrose, talose, sorbose, gulose, idose, and inositol. The invention also relates to an enzymatic process for preparing a hexose from a saccharide by contacting a starch derivative with an immobilized enzyme composition of the invention.

The current disclosure provides a process for enzymatically converting a saccharide into allulose. The invention also relates to a process for preparing allulose where the process involves converting fructose 6-phosphate (F6P) to allulose 6-phosphate (A6P), catalyzed by allulose 6-phosphate 3-epimerase (A6PE), and converting the A6P to allulose, catalyzed by allulose 6-phosphate phosphatase (A6PP).

Disclosed is a new tagatose 6-phosphate 4-epimerase, which is capable of converting fructose 6-phosphate into tagatose 6-phosphate and vice versa. Also disclosed is an application of the enzyme in tagatose production.

The present disclosure is related to biosynthetic methods of forming monosaccharides, and systems for generating the same. A benefit of the methods and systems disclosed herein can include the sustainable production of monosaccharides in an automated process.
