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.

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 ...

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.

Bacteriophage-associated lyase activity against Klebsiella serotype K64 capsular polysaccharide
Carbohydrate Research, 1987Bacteriophage phi 64 possesses a lyase that depolymerises the capsular polysaccharide of Klebsiella K64 into a hexasaccharide having an unsaturated derivative of glucuronic acid at the non-reducing end (1). The unsaturated hex-4-enuronic acid residue generated was characterised spectroscopically (u.v. and n.m.r.) and by g.l.c.-m.s.

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

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).
