Structure and function of a CE4 deacetylase isolated from a marine environment. [PDF]

PLoS ONE, 2017
Chitin, a polymer of β(1-4)-linked N-acetylglucosamine found in e.g. arthropods, is a valuable resource that may be used to produce chitosan and chitooligosaccharides, two compounds with considerable industrial and biomedical potential.

Bioconversion of chitin to chitosan: purification and characterization of chitin deacetylase from Mucor rouxii. [PDF]

Proceedings of the National Academy of Sciences, 1993
Chitin deacetylase, the enzyme that catalyzes the hydrolysis of acetamido groups of N-acetylglucosamine in chitin, has been purified to homogeneity from mycelial extracts of the fungus Mucor rouxii and further characterized. The enzyme exhibits a low pI (approximately 3).

Multi‐omics analysis reveals discordant proteome and transcriptome responses in larval guts of Frankliniella occidentalis infected with an orthotospovirus

Insect Molecular Biology, Volume 34, Issue 5, Page 671-686, October 2025.
Tomato spotted wilt virus modulated the abundance of gut proteins in larval thrips, most notably manifested as a predominant down‐regulation in first instar larvae. Gut‐expressed protein and cognate transcript abundance were moderately correlated across the tissue system; however, the virus effect varied widely at transcriptional and translational ...

Bioactive polysaccharides and their potential health benefits in reducing the risks of metabolic syndrome: A review

Food Biomacromolecules, Volume 2, Issue 3, Page 288-314, September 2025.
Abstract Metabolic syndrome (MetS) is a complex noncommunicable condition characterized by central obesity, insulin resistance, hyperlipidemia, hypertension, and hyperglycemia. Epidemiological evidence shows that MetS affects a third of the global population; however, due to its complex pathogenesis and limited drug therapy options, the increasing ...

Group I chitin deacetylases are essential for higher order organization of chitin fibers in beetle cuticle [PDF]

Journal of Biological Chemistry, 2018
Roles in the organization of the cuticle (exoskeleton) of two chitin deacetylases (CDAs) belonging to group I, TcCDA1 and TcCDA2, as well as two alternatively spliced forms of the latter, TcCDA2a and TcCDA2b, from the red flour beetle, Tribolium castaneum, were examined in different body parts using transmission EM and RNAi.

Enzymatic Modifications of Chitin, Chitosan, and Chitooligosaccharides

Frontiers in Bioengineering and Biotechnology, 2019
Chitin and its N-deacetylated derivative chitosan are two biological polymers that have found numerous applications in recent years, but their further deployment suffers from limitations in obtaining a defined structure of the polymers using traditional ...

Gut Microbiota as a Mediator Between Intestinal Fibrosis and Creeping Fat in Crohn's Disease

United European Gastroenterology Journal, Volume 13, Issue 7, Page 1092-1106, September 2025.
ABSTRACT Intestinal stricture remains one of the most challenging complications in Crohn's disease, and its underlying mechanisms are poorly understood. Accumulating evidence suggests that gut microbiota is significantly altered in stenotic intestines and may play a key role in the development of fibrogenesis in Crohn's disease.

Extremely Low Concentrations of Acetic Acid Stimulate Cell Differentiation in Rice Blast Fungus

iScience, 2020
Summary: Metabolic switching and rewiring play a dynamic role in programmed cell differentiation. Many pathogenic microbes need to survive in nutrient-deficient conditions and use the glyoxylate cycle, an anaplerotic pathway of the tricarboxylic acid ...
