vAL‐1, a novel polysaccharide lyase encoded by chlorovirus CVK2 [PDF]

open access: yesFEBS Letters, 2004
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,

Vibrio cholerae RbmB is an α-1,4-polysaccharide lyase with biofilm-disrupting activity against Vibrio polysaccharide (VPS). [PDF]

open access: yesPLoS Pathog
Many pathogenic bacteria form biofilms as a protective measure against environmental and host hazards. The underlying structure of the biofilm matrix consists of secreted macromolecules, often including exopolysaccharides. To escape the biofilm, bacteria may produce a number of matrix-degrading enzymes, including glycosidic enzymes

Characterization of AlgMsp, an alginate lyase from Microbulbifer sp. 6532A.

open access: yesPLoS ONE, 2014
Alginate is a polysaccharide produced by certain seaweeds and bacteria that consists of mannuronic acid and guluronic acid residues. Seaweed alginate is used in food and industrial chemical processes, while the biosynthesis of bacterial alginate is ...

Influence of the culture conditions on extracellular lyase activity related to K5 polysaccharide

open access: yesBiotechnology Letters, 2000
The K5 capsular polysaccharide antigen of some Escherichia coli strains is the non-sulphated precursor in heparin biosynthesis. It is composed by two components, 16 000 and 1500 Da, whose ratio depends on the activity of the extracellular form of a lyase synthesized by the same K5 producer strain.

Distinct Modes of Hidden Structural Dynamics in the Functioning of an Allosteric Polysaccharide Lyase. [PDF]

open access: yesACS Cent Sci, 2022
Dynamics is an essential process to drive an enzyme to perform a function. When a protein sequence encodes for its three-dimensional structure and hence its function, it essentially defines the intrinsic dynamics of the molecule. The static X-ray crystal structure was thought to shed little insight into the molecule's dynamics until the recently ...

Purification and Characterization of a Novel Alginate Lyase from a Marine Streptomyces Species Isolated from Seaweed

open access: yesMarine Drugs, 2021
Alginate, a natural polysaccharide derived from brown seaweed, is finding multiple applications in biomedicine via its transformation through chemical, physical, and, increasingly, enzymatic processes.

Gellan lyases-novel polysaccharide lyases [PDF]

open access: yesMicrobiology, 1994
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 ...
