Characteristics and applications of alginate lyases: A review

International Journal of Biological Macromolecules, 2020
Brown algae, as the main source of alginate, are a type of marine biomass with a very high output. Alginate, a polysaccharide composed of β-D-mannuronic acid (M) and α-L-guluronic acid (G), has great potential for applications in the food, cosmetic and pharmaceutical industries. Alginate lyases (Alys) can degrade alginate polymers into oligosaccharides

Bacterial alginate lyase highly active on acetylated alginates

Journal of Fermentation and Bioengineering, 1993
Abstract A bacterium (strain A1) isolated from a ditch synthesized three kinds of intracellular alginate lyases: A1-I (molecular weight [M.W.] 60,000), A1-II-1 (M.W. 60,000) and A1-II-2 (M.W. 25,000) in laboratory-scale cultures. However, when cells of strain A1 were grown on an industrial scale, another lyase (A1-III) was produced other than A1-I ...

Bacterial alginate lyase: Characterization of alginate lyase-producing bacteria and purification of the enzyme

Journal of Fermentation and Bioengineering, 1991
Abstract Two kinds of bacteria producing alginate lyase were isolated from ditch sample and they were designated A-1 and A-2 strains. Morphological and physiological properties of the two strains were closely similar to each other, except that the cells of strain A-1 showed flocculation during growth on a medium containing alginate as a carbon source.

Kinetics and specificity of alginate lyases

Hydrobiologia, 1993
A purified preparation of the extracellular alginate lyase has been used to study kinetics and specificity towards purified, homopolymeric fragments of alginate. The enzyme preparation from Bacillus circulans 1351 degraded both block types, although with different efficiency, and thus appears to be nonspecific.

Preparation of Dye-labeled Alginate for the Assay of Alginate Lyase

Bioscience, Biotechnology, and Biochemistry, 1997
Dabsyl-alginate, the dye-labeled substrate of alginate lyase, was prepared. Low-viscosity alginate, which was prepared by enzymatic degradation of sodium alginate, and tetramethylenediamine were conjugated by reductive amination. Then, dabsyl-Cl was coupled with the primary amino group of the aminobutyl-alginate. The assay for endo-alginate lyase using

The Surface Display of the Alginate Lyase on the Cells of Yarrowia lipolytica for Hydrolysis of Alginate

Marine Biotechnology, 2009
The alginate lyase structural gene (AlyVI gene) was amplified from plasmid pET24-ALYVI carrying the alginate lyase gene from the marine bacterium Vibrio sp. QY101 which is a pathogen of Laminaria sp. When the gene was cloned into the multiple cloning site of the surface display vector pINA1317-YlCWP110 and expressed in cells of Yarrowia lipolytica, the

Computer-Aided Rational Design Strategy to Improve the Thermal Stability of Alginate Lyase AlyMc.

Journal of Agricultural and Food Chemistry
Alginate lyase degrades alginate by the β-elimination mechanism to produce unsaturated alginate oligosaccharides (UAOS), which have better bioactivities than saturated AOS.
