Kinetic Modeling of Phosphate‐Based Enzyme Cascade for the Production of Fructose From Starch

ChemFoodChem, Volume 2, Issue 3, September 2026.
A mechanistic kinetic model is developed for a phosphate‐based cascade converting starch to fructose. Mechanistic information was used to formulate rate expression of enzymes, and sensitivity analysis was performed to identify key kinetic parameters for optimization.

The Structure of Maltooctaose-Bound Escherichia coli Branching Enzyme Suggests a Mechanism for Donor Chain Specificity

, 2023
Glycogen is the primary storage polysaccharide in bacteria and animals. It is a glucose polymer linked by α-1,4 glucose linkages and branched via α-1,6-linkages, with the latter reaction catalyzed by branching enzymes.

Insulin release transduction mechanism through acid glucan 1,4-alpha-glucosidase activation is Ca2+ regulated

, 1998
An important signal involved in glucose-stimulated insulin secretion is transduced through the action of a lysosomal acid, glucan 1,4-alpha-glucosidase. We investigated the Ca2+ dependency of this enzyme activity in relation to insulin release.

Engineering Slowly Digestible Starch via Physical and Enzymatic Modification: Structural Mechanisms of Formation

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 5, September 2026.
ABSTRACT Dietary starch varies in digestion rate: Rapidly digestible fractions cause sharp postprandial glucose spikes linked to chronic disease, whereas slowly digestible starch (SDS) breaks down gradually, producing a moderate glycemic response. Increasing SDS content is therefore a key objective in developing carbohydrate‐rich foods with improved ...

Amylosucrase as a Versatile Biocatalyst for Next‐Generation Functional Ingredients: Starch Modification and Glycoside Synthesis

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 5, September 2026.
ABSTRACT Amylosucrase (ASase, E.C. 2.4.1.4) is a transglucosidase that catalyzes α‐glucan synthesis and transglycosylation reactions using sucrose as the sole substrate. Unlike Leloir glycosyltransferases requiring expensive nucleotide sugars, ASases utilize readily available sucrose as a cost‐effective glucose donor, offering economic advantages for ...
