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.

Study on Enzymatic Characteristics of Chitin Deacetylase

, 2011
Chitin deacetylase (CDA) catalyzes the conversion of chitin to chitosan by the deacetylation of N-acetyl-D-glucosamine residues. The results of the fundamental enzymatic properties of chitin deacetylase producing from the high productivity chitin ...

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.

Isolation, characterization, and genome sequencing of a novel chitin deacetylase producing Bacillus aryabhattai TCI-16

Frontiers in Microbiology, 2022
Chitin deacetylase (CDA) is a chitin degradation enzyme that catalyzes the conversion of chitin to chitosan by the deacetylation of N-acetyl-D-glucosamine residues, playing an important role in the high-value utilization of waste chitin.

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 ...

Study of chitin deacetylase enzyme activity

, 1997
The present doctoral dissertation focuses on the study of chitin deacetylase activity, continuing the effort towards the desigh of an enzymatic process for the deacetylation of chitin. A new chitin deacetylase was purified to homogeneity from the culture

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.

Acetylation and accessibility of Cryptococcus neoformans cell wall chitosans influence the strength of host immune responses

The Cell Surface
The fungal pathogen Cryptococcus neoformans causes fatal cryptococcal meningitis, a significant global health risk. Unlike most fungi, C. neoformans expresses chitin deacetylases that convert its cell wall chitin into chitosan, helping to evade chitin ...
