Preparation and properties of α-amylase immobilized on silk fibroin

浙江大学学报. 农业与生命科学版, 2002
Cavernous basified fibroin was prepared from degumed silk which pretreated with dilute alkali solution and served as supporter for immobilization of α-amylase to form the basified fibroin immobilized α-amylase, BFIA.

The Antidiabetic Potential of Alpha‐Mangostin: A Review of Preclinical and Clinical Evidence

AgriFood: Journal of Agricultural Products for Food, EarlyView.
Alpha‐mangostin is a compound from the pericarp of Garcinia mangostana. The antidiabetic effects of alpha‐mangostin include enhancing insulin secretion, improving glucose uptake through GLUT receptor upregulation, reducing oxidative stress and inflammation, promoting wound healing, reducing HbA1C, reducing HOMA‐IR index, and decreased mRNA expressions ...

Bacillus subtilisα-amylase: the rate limiting step of secretion is growth phase-independent [PDF]

FEMS Microbiology Letters, 1999
When Bacillus subtilis alpha-amylase was expressed under the control of sacR in a degU32(Hy) strain, the production of exoenzyme occurred during both the exponential and stationary phases of growth. In each phase, pulse-chase experiments showed that the rate-limiting step of the secretion process was the release of the processed form of the protein in ...

AS‐pHopt: An Optimal pH Prediction Model Enhanced by Active Site of Enzymes

Advanced Intelligent Discovery, EarlyView.
To address the low accuracy of enzyme optimal pH (pHopt) prediction, this study develops active site‐based pHopt (AS‐pHopt), a prediction model enhanced by active site information and pseudo‐label prediction. Integrating key structural and physicochemical features affecting enzyme pHopt, AS‐pHopt uses Evolutionary Scale Modeling (ESM)‐2 with active ...

Innervation of the tubarial glands: A hypothesis‐driven anatomical review

The Anatomical Record, EarlyView.
Abstract The tubarial glands have been described as a macroscopic bilateral glandular complex in the posterolateral nasopharynx near the torus tubarius and the pharyngeal opening of the Eustachian tube. Since their recognition on prostate‐specific membrane antigen‐based imaging, their anatomical classification has remained debated, with converging ...

Synthesis of Benzylidene Analogs of Oleanolic Acid as Potential α-Glucosidase and α-Amylase Inhibitors

Frontiers in Chemistry, 2022
A series of benzylidene analogs of oleanolic acid 4a∼4s were synthesized and assessed for their α-glucosidase and α-amylase inhibitory activities. The results presented that all synthesized analogs exhibited excellent-to-moderate inhibitory effects on α ...

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.

Cloning and expression ofLipomyces starkeyiα-amylase inEscherichia coliand determination of some of its properties [PDF]

FEMS Microbiology Letters, 2004
The Lipomyces starkeyi alpha-amylase (LSA) gene encoding soluble starch-degrading alpha-amylase was cloned and characterized from a derepressed and partially constitutive mutant for both dextranase and amylase activities. The nucleotide (nt) sequence of the cDNA fragment reveals an open reading frame of 1944 bp encoding a 619 amino acid (aa) mature ...
