Variations in Cell Wall-Modifying Enzyme Activities and Physicochemical Properties of Pectin in Kiwifruit during Postharvest Softening [PDF]

Shipin Kexue, 2023
In this study, we monitored changes in fruit hardness, cell wall-modifying enzyme activities such as polygalacturonase (PG), pectin methylesterase (PME), pectin lyases (PL) and β-galactosidase (β-Gal), and physiochemical properties of three cell wall ...

A comparative study of the efficacy of alginate lyases in the presence of metal ions elevated in the cystic fibrosis lung milieu

Biochemistry and Biophysics Reports
Pseudomonas aeruginosa, a common cause of morbidity in cystic fibrosis, chronically infects the patient's lungs by forming an alginate-containing biofilm.

Development and validation of a microarray for the investigation of the CAZymes encoded by the human gut microbiome. [PDF]

PLoS ONE, 2013
Distal gut bacteria play a pivotal role in the digestion of dietary polysaccharides by producing a large number of carbohydrate-active enzymes (CAZymes) that the host otherwise does not produce.

Characterization of a New Biofunctional, Exolytic Alginate Lyase from Tamlana sp. s12 with High Catalytic Activity and Cold-Adapted Features

Marine Drugs, 2021
Alginate, a major acidic polysaccharide in brown algae, has attracted great attention as a promising carbon source for biorefinery systems. Alginate lyases, especially exo-type alginate lyase, play a critical role in the biorefinery process.

Characterization of a Hyaluronic Acid Utilization Locus and Identification of Two Hyaluronate Lyases in a Marine Bacterium Vibrio alginolyticus LWW-9

Frontiers in Microbiology, 2021
Hyaluronic acid (HA) is a negatively charged and linear polysaccharide existing in the tissues and body fluids of all vertebrates. Some pathogenic bacteria target hyaluronic acid for adhesion and/or infection to host cells.

A Polysaccharide Lyase from Stenotrophomonas maltophilia with a Unique, pH-regulated Substrate Specificity [PDF]

Journal of Biological Chemistry, 2014
Polysaccharide lyases (PLs) catalyze the depolymerization of anionic polysaccharides via a β-elimination mechanism. PLs also play important roles in microbial pathogenesis, participating in bacterial invasion and toxin spread into the host tissue via degradation of the host extracellular matrix, or in microbial biofilm formation often associated with ...

A Metagenome‐Assembled Genome Catalog From the Global Ruminant Microbiomes

Animal Research and One Health, EarlyView.
The Ruminant Gastrointestinal MAG Catalog (RGMC) is a comprehensive global resource offering 40,812 strain‐level genomes across 53 bacterial and 4 archaeal classes. It greatly surpasses prior efforts in scale and diversity, serving as an essential foundation for research in ruminant nutrition, microbial function, and methane mitigation.
