Nitric oxide, islet acid glucan-1,4-alpha-glucosidase activity and nutrient-stimulated insulin secretion

, 2000
The mechanism of nutrient-evoked insulin release is clearly complex. One part of that mechanism is postulated to be the activation of the glycogenolytic enzyme acid glucan-1,4-alpha-glucosidase.

Safety evaluation of a food enzyme containing cellulase and endo‐1,3(4)‐β‐glucanase activities from the non‐genetically modified Trichoderma reesei strain DP‐Nzc104 [PDF]

EFSA J
Abstract The food enzyme containing cellulase (4‐(1,3;1,4)‐β‐d‐glucan‐4‐glucanohydrolase, EC 3.2.1.4) and endo‐1,3(4)‐β‐glucanase (3‐(1,3;1,4)‐β‐d‐glucan 3(4)‐glucanohydrolase, EC 3.2.1.6) activities is produced with the non‐genetically modified Trichoderma reesei strain DP‐Nzc104 by Genencor International B.V.

Fabrication of 1,4-alpha-D-glucan glucanohydrolase holding Gel-Scaffolds using Agar-Agar, a natural polysaccharide and Polyacrylamide, a synthetic organic polymer for continuous liquefaction of starch [PDF]

, 2023
1,4-alpha-D-glucan glucanohydrolase is among the most widely used commercial hydrolytic enzymes acting randomly on the glycosidic linkages of starch resulting in its saccharification and liquefaction.

Structural insights into xyloglucan recognition by an ABC transporter from a Gram‐positive, thermophilic bacterium

The FEBS Journal, EarlyView.
Athe_2052 is an ABC transporter substrate‐binding protein that recognizes xyloglucan heptasaccharide (XXXG), a soluble breakdown product of plant xyloglucan. The crystal structure of Athe_2052, together with binding assays and computational modeling, shows how XXXG is recognized by this sugar transporter.

Insulin release transduction mechanism through acid glucan 1,4-α-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-α-glucosidase. We investigated the Ca2+dependency of this enzyme activity in relation to insulin release.

Glucan synthase of Phytophthora sojae [PDF]

, 2002
Glucans, with the (1-3)-b-glucosidic linkage as major feature, are present in most of the higher plants, in many lower plants, as well as in microorganisms (Stone and Clarke, 1992). The synthesis of (1-3)-b-glucan in vivo is catalysed by the enzyme (1-3)-

Combining phenotypic, physiological, and multi‐omics studies to provide new insights on the role of 2,4‐epibrassinolide in regulation of seed shattering in Elymus sibiricus L.

Grassland Research, Volume 5, Issue 3, Page 206-221, September 2026.
Abstract Background Seed shattering limits the production of Elymus sibiricus L., and application of exogenous brassinosteroid significantly alleviates plant organ abscission. Methods To explore the potential regulatory network of brassinosteroid on seed shattering, the abscission zone of E. sibiricus cv. Lanyu No.

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 ...
