A study on structural comparisons of α-chitin extracted from marine crustacean shell waste

Carbohydrate Polymer Technologies and Applications, 2021
In the present study, chitin was extracted from marine crustacean shell waste (shrimp, crab, squilla and lobster) using traditional chemical methods (deproteinisation and demineralization) and its physicochemical and structural properties were ...

Chitin-induced systemic disease resistance in rice requires both OsCERK1 and OsCEBiP and is mediated via perturbation of cell-wall biogenesis in leaves

Frontiers in Plant Science, 2022
Chitin is a well-known elicitor of disease resistance and its recognition by plants is crucial to perceive fungal infections. Chitin can induce both a local immune response and a systemic disease resistance when provided as a supplement in soils.

The kinase LYK5 is a major chitin receptor in Arabidopsis and forms a chitin-induced complex with related kinase CERK1

eLife, 2014
Chitin is a fungal microbe-associated molecular pattern recognized in Arabidopsis by a lysin motif receptor kinase (LYK), AtCERK1. Previous research suggested that AtCERK1 is the major chitin receptor and mediates chitin-induced signaling through ...

Reciprocal Inhibition of Adiponectin and Innate Lung Immune Responses to Chitin and Aspergillus fumigatus [PDF]

, 2019
Chitin is a structural biopolymer found in numerous organisms, including pathogenic fungi, and recognized as an immune-stimulating pathogen associated molecular pattern by pattern recognition molecules of the host immune system.

Studies on Chitin I. Enzymic Degradation of Chitin and Chitin Esters [PDF]

Australian Journal of Biological Sciences, 1954
A study has been made O'f the enzymic degradation of chitin and the sodium salt of chitin sulphuric acid by a chitinase prepared from the intestinal tract of the snail, Helix aspersa. It is shown that, in a citrate-phosphate buffer, the pH for optimum activity is 4.8 for both substrates.

Studies on Chitin. I. Acetylation of Chitin [PDF]

Polymer Journal, 1979
Chitin was converted into diacetylchitin and also into various kinds of acetylchitins. A fully acetylated chitin was prepared by the acetylation of chitin in acetic anhydride—methanesulfonic acid mixture at 0°C overnight, or in acetic anhydride—perchloric acid mixture at 0°C for 3 h.

Effects of Ball Milling, Ultrosonic or Hydrochloric Acid Treatment on the Microstructure and Enzymatic Deacetylation Efficiency of Chitin [PDF]

Shipin Kexue, 2023
Chitin is the second most abundant natural polysaccharide on Earth, which can be deacetylated to produce chitosan. However, due to the high crystallinity and poor solubility of chitin, its efficiency of enzymatic deacetylation is very low. To investigate

A structural and biochemical model of processive chitin synthesis [PDF]

, 2014
Chitin synthases (CHS) produce chitin, an essential component of the fungal cell wall. The molecular mechanism of processive chitin synthesis is not understood, limiting the discovery of new inhibitors of this enzyme class.

Cryptococcus neoformans chitin synthase 3 plays a critical role in dampening host inflammatory responses [PDF]

, 2020
Cryptococcus neoformans is the most common disseminated fungal pathogen in AIDS patients, resulting in ∼200,000 deaths each year. There is a pressing need for new treatments for this infection, as current antifungal therapy is hampered by toxicity and/or
