RNA interference of trehalose-6-phosphate synthase and trehalase genes regulates chitin metabolism in two color morphs of Acyrthosiphon pisum Harris

Scientific Reports, 2021
Trehalose-6-phosphate synthase (TPS) and trehalase (TRE) directly regulate trehalose metabolism and indirectly regulate chitin metabolism in insects. Real-time quantitative PCR (RT-qPCR) and RNA interference (RNAi) were used to detect the expressions and

Chitin Deacetylases Are Required for Epichloë festucae Endophytic Cell Wall Remodeling During Establishment of a Mutualistic Symbiotic Interaction with Lolium perenne

Molecular Plant-Microbe Interactions, 2021
Epichloë festucae forms a mutualistic symbiotic association with Lolium perenne. This biotrophic fungus systemically colonizes the intercellular spaces of aerial tissues to form an endophytic hyphal network and also grows as an epiphyte.

Diet-Driven Divergence in Gut Microbiota Variation Between Two Sympatric Gerbil Species. [PDF]

Ecol Evol
ABSTRACT Gut microbiota provide various benefits to their mammalian hosts; however, knowledge regarding interspecific differences in gut microecology remains limited. This study employed 16S rRNA sequencing combined with metagenomic functional prediction (potential functions or functional potential) to conduct a comparative analysis of the gut ...

Bioproduction of Chitooligosaccharides: Present and Perspectives

Marine Drugs, 2014
Chitin and chitosan oligosaccharides (COS) have been traditionally obtained by chemical digestion with strong acids. In light of the difficulties associated with these traditional production processes, environmentally compatible and reproducible ...

Purification and Characterization of Chitin Deacetylase from Colletotrichum lindemuthianum [PDF]

Journal of Biological Chemistry, 1995
Chitin deacetylase (EC 3.5.1.41), the enzyme that catalyzes the hydrolysis of acetamido groups of N-acetyl-D-glucosamine in chitin, has been purified to homogeneity from the culture filtrate of the fungus Colletotrichum lindemuthianum and further characterized.

Can we make Chitosan by Enzymatic Deacetylation of Chitin?

Molecules, 2019
Chitin, an insoluble linear polymer of β-1,4-N-acetyl-d-glucosamine (GlcNAc; A), can be converted to chitosan, a soluble heteropolymer of GlcNAc and d-glucosamine (GlcN; D) residues, by partial deacetylation.

Purificação e caracterização da quitinase de uva (Vitis vinífera L. cv Red Globe) para a produção de quitosana a partir de quitina de camarão

Química Nova, 2010
Chitinase is produced by a wide variety of plants as a defense against peste attacks. In this study, grape chitinases were purified 16 times by fractionation in 80% ammonium sulfate followed by dialysis and filtration.

The Primary Structure of a Fungal Chitin Deacetylase Reveals the Function for Two Bacterial Gene Products.

, 1993
Chitin deacetylase (EC 3.5.1.41) hydrolyzes the N-acetamido groups of N-acetyl-D-glucosamine residues in chitin. A cDNA to the Mucor rouxii mRNA encoding chitin deacetylase was isolated, characterized, and sequenced. Protein sequence comparisons revealed

Insights Into the Role of Lysine Acetylation of Non‐Histone Proteins in Plant Immunity

Plant, Cell &Environment, EarlyView.
ABSTRACT Plant immunity is regulated by numerous transcriptional and posttranslational mechanisms. Among these, lysine acetylation, which is controlled by lysine acetyltransferases (KATs) and lysine deacetylases (KDACs), has been extensively studied, particularly in the context of epigenetic regulation through histone acetylation.
