Mechanistic Insights into Substrate Recognition and Catalysis of a New Ulvan Lyase of Polysaccharide Lyase Family 24. [PDF]

Appl Environ Microbiol, 2021
Ulvan is a major cell wall component of green algae of the genus Ulva. Many marine heterotrophic bacteria can produce extracellular ulvan lyases to degrade ulvan for a carbon nutrient. In addition, ulvan has a range of physiological bioactivities based on its specific chemical structure.

Revised domain structure of ulvan lyase and characterization of the first ulvan binding domain. [PDF]

Sci Rep, 2017
AbstractBiomass waste products from green algae have recently been given new life, as these polysaccharides have potential applications in industry, agriculture, and medicine. One such polysaccharide group called ulvans displays many different, potentially useful properties that arise from their structural versatility.

A new carbohydrate-active oligosaccharide dehydratase is involved in the degradation of ulvan. [PDF]

J Biol Chem, 2021
Marine algae catalyze half of all global photosynthetic production of carbohydrates. Owing to their fast growth rates, Ulva spp. rapidly produce substantial amounts of carbohydrate-rich biomass and represent an emerging renewable energy and carbon ...

A novel ulvan lyase family with broad-spectrum activity from the ulvan utilisation loci of Formosa agariphila KMM 3901. [PDF]

Sci Rep, 2018
AbstractUlvan, which is one of the major structural polysaccharides of the cell walls of green macroalgae, is degraded by ulvan lyases via the β-elimination mechanism with the release of oligosaccharides that have unsaturated 4-deoxy-L-threo-hex-4-enopyranosiduronic acid (∆) at the non-reducing end. These ulvan lyases belong to the PL24 or PL25 or PL28

Pseudoalteromonas agarivorans-derived novel ulvan lyase of polysaccharide lyase family 40: Potential application of ulvan and partially hydrolyzed products in cosmetic industry. [PDF]

J Ind Microbiol Biotechnol
Abstract   Ulvan is a complex sulfated polysaccharide in the cell walls of green algae with extensive applications in food, pharmaceutical, and agricultural industries, prompting extensive studies on ulvan, its oligosaccharides, monosaccharides, and cost-effective depolymerization methods. Our primary

Structural and functional characterization of PL28 family ulvan lyase NLR48 from Nonlabens ulvanivorans. [PDF]

J Biol Chem, 2018
Ulvan is a complex sulfated polysaccharide present in the cell wall of green algae of the genus Ulva (Chlorophyta). The first ulvan-degrading polysaccharide lyases were identified several years ago, and more were discovered through genome sequencing of marine bacteria. Ulvan lyases are now grouped in three polysaccharide lyase (PL) families in the CAZy

Biochemical characterization of a novel ulvan lyase from Pseudoalteromonas sp. strain PLSV. [PDF]

RSC Adv, 2018
Ulvans, complex polysaccharides found in the ulvales (green seaweed) cell wall, contain predominantly 3-sulfated rhamnose (Rha3S) linked to either d-glucuronic acid, l-iduronic acid or d-xylose.

Sulfation of Arabinogalactan Proteins Confers Privileged Nutrient Status to Bacteroides plebeius [PDF]

, 2021
The human gut microbiota (HGM) contributes to the physiology and health of its host. The health benefits provided by dietary manipulation of the HGM require knowledge of how glycans, the major nutrients available to this ecosystem, are metabolized ...
