Alginate is an anionic polysaccharide abundantly present in the cell walls of brown macroalgae. The enzymatic depolymerization is performed solely by alginate lyases (EC 4.2.2.x), categorized as polysaccharide lyases (PLs) belonging to 12 different PL ...

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 ...

Exploring molecular determinants of polysaccharide lyase family 6–1 enzyme activity [PDF]
Abstract The polysaccharide lyase family 6 (PL6) represents one of the 41 polysaccharide lyase families classified in the CAZy database with the vast majority of its members being alginate lyases grouped into three subfamilies, PL6_1–3. To decipher the mode of recognition and action of the enzymes belonging to subfamily PL6_1, we solved ...

Fucoidans represent a type of polyanionic fucose-containing sulfated polysaccharides (FCSPs) that are cleaved by fucoidan-degrading enzymes, producing low-molecular-weight fucoidans with multiple biological activities suitable for pharmacological use ...

Polysaccharide lyases from gellan-producing Sphingomonas spp. [PDF]
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 ...

Phylogenetic Distribution of Polysaccharide-Degrading Enzymes in Marine Bacteria
Deconstruction is an essential step of conversion of polysaccharides, and polysaccharide-degrading enzymes play a key role in this process. Although there is recent progress in the identification of these enzymes, the diversity and phylogenetic ...

Genome-Wide Analysis of PL7 Alginate Lyases in the Genus Zobellia
We carried out a detailed investigation of PL7 alginate lyases across the Zobellia genus. The main findings were obtained using the methods of comparative genomics and spatial structure modeling, as well as a phylogenomic approach. Initially, in order to

vAL‐1, a novel polysaccharide lyase encoded by chlorovirus CVK2 [PDF]
Cell wall materials isolated from Chlorella cells were degraded by the polysaccharide‐degrading enzyme vAL‐1 encoded by chlorovirus CVK2. Matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometric analyses of the degradation products (oligosaccharides) revealed major oligosaccharides contain unsaturated GlcA at the reducing terminus,
