Probing the pH Effects on Sugar Binding to a Polysaccharide Lyase [PDF]

The Journal of Physical Chemistry B, 2019
Polysaccharide lyases (PLs) are an important class of proteins that are excreted from bacteria to degrade sugars in the extracellular matrix of the host. The PL from S. maltophilia (Smlt1473) was found to have pH-specific degradation of three varying polysaccharides: alginate, celluronic acid, and hyaluronic acid (J. Biol. Chem. 2014, 289, 18022-18032).

Alginate Lyases: Sources, Mechanism of Activity and Potencial Application

Squalen, 2013
Alginate lyases are group of enzymes which catalyze depolymerization of alginate into oligosaccharides. Alginate lyase have been widely used in many applications such as in production of bioactive oligosaccharides, control of polysaccharide rheological ...

Functional Characterization of Carbohydrate-Binding Modules in a New Alginate Lyase, TsAly7B, from Thalassomonas sp. LD5

Marine Drugs, 2019
Alginate lyases degrade alginate into oligosaccharides, of which the biological activities have vital roles in various fields. Some alginate lyases contain one or more carbohydrate-binding modules (CBMs), which assist the function of the catalytic ...

Three alginate lyases provide a new gut Bacteroides ovatus isolate with the ability to grow on alginate

Applied and Environmental Microbiology, 2023
Humans consume alginate in the form of seaweed, food hydrocolloids, and encapsulations, making the digestion of this mannuronic acid (M) and guluronic acid (G) polymer of key interest for human health. To increase knowledge on alginate degradation in the

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 ...

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.
