Polysaccharide Lyases: Recent Developments as Biotechnological Tools
Critical Reviews in Biotechnology, 2003Polysaccharide lyases, which are polysaccharide cleavage enzymes, act mainly on anionic polysaccharides. Produced by prokaryote and eukaryote organisms, these enzymes degrade (1,4) glycosidic bond by a beta elimination mechanism and have unsaturated oligosaccharides as major products.

A Structural Basis for Depolymerization of Alginate by Polysaccharide Lyase Family-7
Journal of Molecular Biology, 2005Alginate lyases depolymerize alginate, a heteropolysaccharide consisting of alpha-L-guluronate and beta-D-mannuronate, through a beta-elimination reaction. Their structure/function relationships are expected to provide information valuable to future industrial alginate processing and drug design for Pseudomonas aeruginosa alginate biofilm-dependent ...

Probing the pH Effects on Sugar Binding to a Polysaccharide Lyase
The Journal of Physical Chemistry B, 2019Polysaccharide 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).

Cells of Bacillus sp. GL1 extracellularly secrete a gellan lyase with a molecular mass of 130 kDa responsible for the depolymerization of a heteropolysaccharide (gellan), although the gene is capable of encoding a huge protein with a molecular mass of 263 kDa.

Analysis of Glycosaminoglycans with Polysaccharide Lyases
Current Protocols in Molecular Biology, 1999Polysaccharide lyases are a class of enzymes useful for analysis of glycosaminoglycans (GAGs) and the glycosaminoglycan component of proteoglycans (PGs). These enzymes cleave specific glycosidic linkages present in acidic polysaccharides and result in depolymerization.

A thermostable, alkaline rhamnogalacturonan lyase (RG lyase) CtRGLf, of family 11 polysaccharide lyase from Clostridium thermocellum was cloned, expressed, purified and biochemically characterised. Both, the full-length CtRGLf (80 kDa) protein and its truncated derivative CtRGL (63.9 kDa) were expressed as soluble proteins and displayed maximum ...

Bioprocess and Biosystems Engineering
Enhancing the stability and the reusability of ulva polysaccharide lyase (UPL) is crucial for the efficient production of reducing sugars from ulva polysaccharides, which are vital for their broad applications in functional foods. In this study, we innovatively developed a self-immobilized UPL by fusing the enzyme with ferritin, leading to the ...

An engineered polysaccharide lyase to combat harmful algal blooms
Biochemical Engineering Journal, 2018Abstract A growing global population and industrialization have come at the cost of induced climate change and pollution of natural resources, resulting in formation of toxic algal blooms in fresh water sources. In the US alone, these blooms cost an estimated $1.5 billion dollars each year to remediate.

Klebsiella K14 capsular polysaccharide was degraded by a bacteriophage-borne enzyme to afford oligosaccharides A-C which were studied by one- and two-dimensional n.m.r. spectroscopy. A and B were the repeating-unit hexasaccharide and pyruvylated hexasaccharide, respectively, while C was a dodecasaccharide.
