Alginate and its derivatives are annually produced approximately 30,000 tons or more and are applied to various industries as they are natural polymers. The global market for alginate and its derivatives has been growing steadily. There is little research compared to other enzymes produced through biomass degradation or modification. An alginate lyase,

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).

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 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 ...

The first structure of pectate lyase belonging to polysaccharide lyase family 3
Acta Crystallographica Section D Biological Crystallography, 2001The crystal structure of a highly alkaline low molecular weight pectate lyase (Pel-15) was determined at 1.5 A resolution by the multiple isomorphous replacement (MIR) method. This is the first pectate lyase structure from polysaccharide lyase family 3.

A typical filamentous bacterium, Sphaerotilus natans, secretes a thiolic glycoconjugate which is assembled into a microtube, so called sheath. The glycoconjugate is known to consist of a pentasaccharide-dipeptide repeating unit, but its chemical structure has not been completely elucidated.

Structural Analyses of Substrate–pH Activity Pairing Observed across Diverse Polysaccharide Lyases
Biochemistry, 2023Anionic polysaccharides found in nature are functionally and structurally diverse, and so are the polysaccharide lyases (PLs) that catalyze their degradation. Atomic superposition of various PL folds according to their cleavable substrate structure confirms the occurrence of structural convergence at PL active sites. This suggests that various PL folds

Improvement of expression level of polysaccharide lyases with new tag GAPDH in E. coli
Journal of Biotechnology, 2016Escherichia coli (E. coli) is widely used to express a variety of heterologous proteins. Efforts have been made to enhance the expression level of the desired protein. However, problems still exist to regulate the level of protein expression and therefore, new strategies are needed to overcome those issues.

A thio-linked disaccharide based on the structure of the glycosaminoglycan chondroitin was synthesized as a potential inhibitor of chondroitin AC lyase from Flavobacterium heparinum for structural analysis of the active site. Instead it was found to be a slow substrate, thereby demonstrating that lyases, in contrast to glycosidases, can cleave ...
