Ulvan Lyases Isolated from the Flavobacteria Persicivirga ulvanivorans Are the First Members of a New Polysaccharide Lyase Family [PDF]
Journal of Biological Chemistry, 2011 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.

Polysaccharide lyases from gellan-producing Sphingomonas spp. [PDF]
Microbiology, 1996 A number ofSphingomonasstrains capable of synthesizing the bacterial exopolysaccharide gellan and related polymers were shown to possess constitutive gellanase activity. In each case, the degradation of deacylated gellan was due to extracellular, eliminase-type enzymes (lyases) which cleave the sequence …ß-D-glucosyl 1,4-ß-D-glucuronosyl… in the ...

Unraveling the molecular mechanism of polysaccharide lyases for efficient alginate degradation [PDF]
Nature CommunicationsAlginate lyases (ALs) are essential for breaking down brown macroalgae alginates, widely used naturally-occurring polysaccharides. Their molecular mechanisms remain challenging due to the lack of catalytically competent Michaelis-Menten complex structures.
