Key virulence genes associated with Streptococcus mutans biofilm formation: a systematic review

Frontiers in Oral Health
IntroductionStreptococcus mutans is central to plaque-induced oral diseases due to its robust biofilm-forming ability. Understanding the genetic and regulatory basis of this process is critical for developing targeted anti-virulence strategies that ...

Produção de isomaltulose, um substituto da sacarose, utilizando glicosiltransferase microbiana Isomaltulose production, a new sucrose substitute, using microbial glucosyl transferase

Química Nova, 2008
Isomaltulose, a functional isomer of sucrose, is a non-cariogenic reducing disaccharide; has a low glycemic index; selectively promotes growth of beneficial bifidobacteria in the human intestinal microflora; and has greater stability than sucrose in some

Inhibition of Clostridium difficile TcdA and TcdB toxins with transition state analogues

Nature Communications, 2021
The Clostridium difficile virulence factors TcdA and TcdB contain a glucosyltransferase domain (GTD), which has both glucohydrolase (GH) and glucosyltransferase (GT) activities. Here, the authors characterize the transition state features of the TcdA and

Glucosyltransferase CsUGT78A14 Regulates Flavonols Accumulation and Reactive Oxygen Species Scavenging in Response to Cold Stress in Camellia sinensis

Frontiers in Plant Science, 2019
Glycosyltransferases (UGTs) play diverse roles in cellular metabolism by altering regulatory metabolites activities. However, the physiological roles of most members of UGTs in crops in response to abiotic stresses are unknown. We have identified a novel

Allelic Variation in gtfB–gtfC Region of Natural Variant of Streptococcus mutans Without Biofilm Formation

Bacteria
Streptococcus mutans is primarily found in biofilms on tooth surfaces and is associated with the development of dental caries. S. mutans synthesizes water-insoluble glucan (WIG) using sucrose as a substrate, inducing the formation of three-dimensional ...

Inhibition of Glucosyltransferase Activity and Glucan Production as an Antibiofilm Mechanism of Lemongrass Essential Oil against Escherichia coli O157:H7

Antibiotics, 2020
The resistance of Escherichia coli O157:H7 to disinfection is associated with its ability to form biofilms, mainly constituted by glucans produced by glucosyltransferases.

Molecular Characterization of an EMS-Induced Ab-γg-Rich Saponin Mutant in Soybean (Glycine max (L.) Merr.)

Agronomy
Soybean is particularly known for accumulating saponins in its seeds. This study aimed to identify a causal gene to control an increase in Ab-γg saponin in PE1607 from an EMS-treated population of the soybean cultivar Pungsannamul.
