Engineering of Cyclodextrin Product Specificity and pH Optima of the Thermostable Cyclodextrin Glycosyltransferase from Thermoanaerobacterium thermosulfurigenes EM1 [PDF]

, 1998
The product specificity and pH optimum of the thermostable cyclodextrin glycosyltransferase (CGTase) from Thermoanaerobacterium thermosulfurigenes EM1 was engineered using a combination of x-ray crystallography and site-directed mutagenesis.

Acute pancreatitis associated with lamivudine therapy for chronic B hepatitis

Brazilian Journal of Infectious Diseases
Hyperamylasemia is a common complication during lamivudine use. We report a case of a pancreatitis following lamivudine therapy. A careful monitoring of amylase levels during treatment with lamivudine is discussed, mainly in the first weeks, considering ...

The Extract of Viola odorata Flowers Improves the Biochemical, Pancreas Histological, and Insulin Resistance Parameters in an Animal Model of Diabetes

Iranian Journal of Toxicology, 2022
Background: The antioxidant defense in the pancreas is low because they are exposed to toxic substances daily. This study aimed to evaluate the ameliorating effect of Viola odorata flowers Extract (VOE) on the pancreas histology and function in ...

Bioactive Products From Plant-Endophytic Gram-Positive Bacteria

Frontiers in Microbiology, 2019
Endophytes constitute plant-colonizing microorganisms in a mutualistic symbiosis relationship. They are found in most ecosystems reducing plant crops’ biotic and abiotic stressors by stimulating immune responses, excluding plant pathogens by niche ...

Activity of Hydrolases and Their Inhibitors in Potato Plants Treated with Bacillus subtilis, Salicylic, and Jasmonic Acids and Affected by the Combined Effect of the Late Blight and the Lack of Moisture

International Journal of Plant Biology, 2023
The effect of Bacillus subtilis in combination with salicylic (SA) and jasmonic (JA) acids on the activity of amylases, cellulases, proteases, and their inhibitors in potato leaves in connection with the development of resistance to Phytophthora ...

Hosts and Commensal Bacteria Synergistically Antagonize Opportunistic Pathogens at the Single‐Cell Resolution

Advanced Science, EarlyView.
In the tripartite‐species model, Drosophila larvae stimulate lactate production through excreting digestion enzymes. S. marcescens population senses a cue of lactate and tends to diverge into virulent and reduced virulence subclusters with remarkable heterogeneity to metabolize carbon metabolism and counter colonization resistance, giving a fitness ...

Functional relationships between cyclodextrin glucanotransferase from an alkalophilic Bacillus and α-amylases Site-directed mutagenesis of the conserved two Asp and one Glu residues [PDF]

, 1992
Comparison of the amino acid sequences of cyclodextrin glucanotransferases (CGTases) with those of α-amylases revealed that two Asp and one Glu residues, which are considered to be the catalytic residues in α-amylases, were also conserved in CGTases.

Gasdermin D‐Mediated Pyroptosis Exerts Two Opposite Effects of Resisting Enzymatic Digestion and Expanding Inflammatory Response in Acute Pancreatitis

Advanced Science, EarlyView.
Gasdermin D (GSDMD) does not only reduce pancreatic enzyme synthesis but also induces pancreatic acinar cells to express mucin 1 (MUC1), which forms a barrier to prevent digestive enzyme‐mediated digestion. However, GSDMD can promote the secretion of inflammatory cytokines by macrophages and aggravate pancreatic histological injury by expanding ...

Divergent taxonomic and functional responses of microbial communities to field simulation of aeolian soil erosion and deposition. [PDF]

, 2017
Aeolian soil erosion and deposition have worldwide impacts on agriculture, air quality and public health. However, ecosystem responses to soil erosion and deposition remain largely unclear in regard to microorganisms, which are the crucial drivers of ...

Assembling Hexahedral Supramolecular Nano‐Aggregates on Rice Wax Layer Matrices to Promote the Leaf Deposition and Bioavailability of Bactericides for Plant Protections

Advanced Science, EarlyView.
To address the problem of off‐target movement and low bioavailability of pesticides, two anisotropic supramolecular building units (BiTA18@β‐CD and BiTA18@γ‐CD) have been invented that can self‐assemble into nano‐sized hexagonal cuboids on the rice microcrystalline matrix. This manipulation realizes the enhanced utilization of bactericides for rice and
