Characterization of the thermophilic xylanase Fsa02490Xyn from the hyperthermophile Fervidibacter sacchari belonging to glycoside hydrolase family 10. [PDF]

FEBS Open Bio
Fervidibacter sacchari is a member of the bacterial phylum Armatimonadota, only a few of which have been cultivated. It is a hyperthermophilic polysaccharide degradation specialist. We show that a secreted enzyme, Fsa02490Xyn, is an endoxylanase belonging to glycoside hydrolase family 10.

Genetic dissection of monosaccharides contents in rice whole grain using genome‐wide association study

The Plant Genome, Volume 16, Issue 4, December 2023., 2023
Abstract The simplest form of carbohydrates are monosaccharides which are the building blocks for the synthesis of polymers or complex carbohydrates. Monosaccharide contents of 197 rice accessions were quantified by HPAEC‐PAD in rice (Oryza sativa L.) whole grain (RWG).

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

Mass 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.

Marine Bacteroidetes enzymatically digest xylans from terrestrial plants

Environmental Microbiology, Volume 25, Issue 9, Page 1713-1727, September 2023., 2023
Abstract Marine Bacteroidetes that degrade polysaccharides contribute to carbon cycling in the ocean. Organic matter, including glycans from terrestrial plants, might enter the oceans through rivers. Whether marine bacteria degrade structurally related glycans from diverse sources including terrestrial plants and marine algae was previously unknown. We

Discovery of a bifunctional xylanolytic enzyme with arabinoxylan arabinofuranohydrolase‐d3 and endo‐xylanase activities and its application in the hydrolysis of cereal arabinoxylans

Microbial Biotechnology, Volume 16, Issue 7, Page 1536-1547, July 2023., 2023
1. A novel bifunctional xylanolytic enzyme (rAbf43A) was obtained.2. rAbf43A exhibits arabinoxylan arabinofuranohydrolase‐d3 and endo‐xylanase activities.3. rAbf43A shows obvious synergy with cognate bifunctional xylanase/feruloyl esterase. Abstract Xylanolytic enzymes, with both endo‐xylanase and arabinoxylan arabinofuranohydrolase (AXH) activities ...

Grass xylan structural variation suggests functional specialization and distinctive interaction with cellulose and lignin

The Plant Journal, Volume 113, Issue 5, Page 1004-1020, March 2023., 2023
SUMMARY Xylan is the most abundant non‐cellulosic polysaccharide in grass cell walls, and it has important structural roles. The name glucuronoarabinoxylan (GAX) is used to describe this variable hemicellulose. It has a linear backbone of β‐1,4‐xylose (Xyl) residues that may be substituted with α‐1,2‐linked (4‐O‐methyl)‐glucuronic acid (GlcA), α‐1,3 ...

Hemicellulose‐remodelling transglycanase activities from charophytes: towards the evolution of the land‐plant cell wall

The Plant Journal, Volume 108, Issue 1, Page 7-28, October 2021., 2021
Significance Statement Transglycanase enzymes remodel land‐plant cell walls, enabling wall restructuring. Unfortunately, comparable enzymes in charophytes (the land plants’ closest algal relatives) are little known, limiting our understanding of the ‘alga to land plant’ transition.

Marine Polysaccharides: Occurrence, Enzymatic Degradation and Utilization

ChemBioChem, Volume 22, Issue 13, Page 2247-2256, July 1, 2021., 2021
Algae biomass is a source for many valuable compounds for the pharmaceutical and chemical industry. Especially marine polysaccharides contain rare sugars of interest, but a major bottleneck is access to these sugars. In this mini‐review the common knowledge of marine CAZyme‐based deconstruction of these polysaccharides and the biotechnological ...

Glucose Modulates Marine Xylanase Activity: Insights From Caulerpa lentillifera and Synthetic β‐1,3‐glucoxylans

ChemBioChem, Volume 27, Issue 13, 14 July 2026.
Two recombinant xylanases from marine bacteria, β‐1,3‐xylanase Xyl4 and mixed‐linkage xylanase AlXyn26A, were used to digest glucoxylan structures extracted from the green alga Caulerpa lentillifera and synthesized by automated glycan assembly. High‐performance liquid chromatography coupled with mass spectrometry (HPLC‐MS) analysis of the reaction ...
