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

Rhamnogalacturonan lyase reveals a unique three‐domain modular structure for polysaccharide lyase family 4 [PDF]
Rhamnogalacturonan lyase (RG‐lyase) specifically recognizes and cleaves α‐1,4 glycosidic bonds between l‐rhamnose and d‐galacturonic acids in the backbone of rhamnogalacturonan‐I, a major component of the plant cell wall polysaccharide, pectin.

The K5 Lyase KflA Combines a Viral Tail Spike Structure with a Bacterial Polysaccharide Lyase Mechanism [PDF]
K5 lyase A (KflA) is a tail spike protein (TSP) encoded by a K5A coliphage, which cleaves K5 capsular polysaccharide, a glycosaminoglycan with the repeat unit [-4)-betaGlcA-(1,4)- alphaGlcNAc(1-], displayed on the surface of Escherichia coli K5 strains.

Novel Molecular Insights into the Catalytic Mechanism of Marine Bacterial Alginate Lyase AlyGC from Polysaccharide Lyase Family 6. [PDF]
Alginate lyases that degrade alginate via a β-elimination reaction fall into seven polysaccharide lyase (PL) families. Although the structures and catalytic mechanisms of alginate lyases in the other PL families have been clarified, those in family PL6 have yet to be revealed.

Ulvan Lyases Isolated from the Flavobacteria Persicivirga ulvanivorans Are the First Members of a New Polysaccharide Lyase Family [PDF]
Ulvans are complex sulfated polysaccharides found in the cell walls of green algae belonging to the genus Ulva. These polysaccharides are composed of disaccharide repetition moieties made up of sulfated rhamnose linked to either glucuronic acid, iduronic acid, or xylose.

Gellan lyases-novel polysaccharide lyases [PDF]
A number of bacterial strains capable of degrading the bacterial exopolysaccharide gellan have been isolated by standard enrichment procedures. They include several pink-pigmented Gram-negative rod-shaped bacteria. A red-pigmented Gram-positive bacillus earlier found to degrade the exopolysaccharide xanthan from Xanthomonas campestris also showed ...

Polysaccharide lyases are the products of various microorganisms, bacteriophage and some eukaryotes. All such enzymes cleave a hexose-1,4-alpha- or beta-uronic acid sequence by beta-elimination. They are in some examples, the only known type of enzymes degrading their polyanionic substrates.

Diversity and function of phage encoded depolymerases [PDF]
Bacteriophages of the Podoviridae family often exhibit so-called depolymerases as structural components of the virion. These enzymes appear as tail spike proteins (TSPs).
