Analysis of the structure and substrate scope of chitooligosaccharide oxidase reveals high affinity for C2‐modified glucosamines [PDF]

open access: yesFEBS Letters, Volume 594, Issue 17, Page 2819-2828, September 2020., 2020
The crystal structure of ChitO was solved for the first time. The substrate range of ChitO was further expanded towards C2‐glucosamines. Docking experiments explained the substrate acceptance of ChitO. Chitooligosaccharide oxidase (ChitO) is a fungal carbohydrate oxidase containing a bicovalently bound FAD cofactor.

Structure and function of a broad-specificity chitin deacetylase from Aspergillus nidulans FGSC A4 [PDF]

open access: yesScientific Reports, 2017
Enzymatic conversion of chitin, a β-1,4 linked polymer of N-acetylglucosamine, is of major interest in areas varying from the biorefining of chitin-rich waste streams to understanding how medically relevant fungi remodel their chitin-containing cell ...

Comparing the Antibacterial Properties of Chitin, Chitosan and Chito-oligomers Extracted from Shell of Metapenaeus affinis

open access: yesJournal of Mazandaran University of Medical Sciences, 2017
Background and purpose: Chitin is one of the main components of crustaceans’ exoskeleton. Chitosan is produced by deacetylation of chitin. Molecular weight and degree of deacetylation play important roles in biological activity of chitin, chitosan, and ...

Synthesis of Fungal Cell Wall Oligosaccharides and Their Ability to Trigger Plant Immune Responses. [PDF]

open access: yesEuropean J Org Chem, 2022
Automated glycan assembly and solution‐phase synthesis provided a set of fungal cell wall oligosaccharides that were investigated for their ability to activate the plant immune system. Synthetic chitin and β‐1,6‐glucan oligosaccharides triggered mitogen‐activated protein kinase phosphorylation and a reactive oxygen burst in Arabidopsis seedlings ...

Chitin and Chitosan Binding to the α-Chitin Crystal: A Molecular Dynamics Study. [PDF]

open access: yesACS Omega, 2023
Understanding the binding of chitosan oligomers to the surface of a chitin nanocrystal is important for improving the enzymatic deacetylation of chitin and for the design of chitin/chitosan composite films.

Biochemical and Structural Characterization of a Uronic Acid Oxidase from Citrus sinensis

open access: yesChemCatChem, Volume 15, Issue 21, November 8, 2023., 2023
Aldaric acids are attractive diacids that can be prepared by selective oxidation of carbohydrates. The discovery, biochemical and structural characterization of a VAO‐type flavin‐containing carbohydrate oxidase from Citrus sinensis: URAOCs3 is reported. The selective oxidation of D‐galacturonic acid in a complex mixture is demonstrated.

Analysis of carbohydrates and glycoconjugates by matrix‐assisted laser desorption/ionization mass spectrometry: An update for 2019–2020

open access: yesMass Spectrometry Reviews, Volume 42, Issue 5, Page 1984-2206, September/October 2023., 2023
Abstract This review is the tenth update of the original article published in 1999 on the application of matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry to the analysis of carbohydrates and glycoconjugates and brings coverage of the literature to the end of 2020.

Revisiting the AA14 family of lytic polysaccharide monooxygenases and their catalytic activity

open access: yesFEBS Letters, Volume 597, Issue 16, Page 2086-2102, August 2023., 2023
The AA14 family of lytic polysaccharide monooxygenases (LPMOs) was discovered in 2018. While these enzymes were originally thought to act on cellulose‐associated xylan, thorough characterization of both a novel and previously studied family members indicates that AA14 LPMOs do not act on cellulose‐associated xylan.

Effects of chitin and chitosan on root growth, biochemical defense response and exudate proteome of Cannabis sativa

open access: yesPlant-Environment Interactions, Volume 4, Issue 3, Page 115-133, June 2023., 2023
Chitosan elicits defense responses of Cannabis sativa root systems, but chitin has no effect in this regard. Defense enzymes and proteins were found to be increasingly produced in the tissues and secreted into exudate upon chitosan treatment. These results highlight the potential of chitosan to be alternatively used for managing fungal infection in ...
