General description

Alginate lyases is present in several marine algae, marine mollusks and a vast range of marine and terrestrial bacteria.

Application

Alginate Lyase has been used:
  • in the pre-processing of enzyme
  • to de-encapsulate cells
  • to digest Pseudomonas exopolysaccharide to facilitate electroporation

Alginate Lyase is used to break down alginate or alginic acid and to reduce viscosity. It is useful during follicle isolation, encapsulation, and culture .

Biochem/physiol Actions

Alginate lyases actively participates in the saccharification of the acidic polysaccharides for the production of bioethanol.
Breaks down alginate or alginic acid to smaller molecules and reduces viscosity.

Unit Definition

One unit will produce an increase the A235nm of 1.0 per minute per mL of sodium alginate solution at pH 6.3 at 37 °C

Preparation Note

Add 0.15 mI of enzyme solution (1 un/ml) to 4.5 ml of 0.1% sodium alginate (pH 6.3). Incubate at 37 °C for 30 minutes. Terminate reaction by addition of 4.65 ml of 0.1 N NaOH.

A bacterium, Sphingomonas sp. strain A1, can incorporate alginate into cells through a novel ABC (ATP-binding cassette) transporter system specific to the macromolecule. The transported alginate is depolymerized to di- and trisaccharides by three kinds of cytoplasmic alginate lyases (A1-I

We report a method for wrapping tissues with a pre-established cage-like layer composed of living cells. We encapsulated multicellular aggregates of human hepatoma HepG2 cells as a model of tissues such as pancreatic islets and hepatocyte spheroids in alginate-based hydrogel

Alginate constitutes a significant part of seaweed biomass and thus a crucial nutrient for numerous marine heterotrophic bacteria. However, the mechanisms for alginate assimilation remain largely unknown in marine microorganisms. We show here that the genome of the marine flavobacterium
