Alginate lyases is present in several marine algae, marine mollusks and a vast range of marine and terrestrial bacteria.
Application
Alginate Lyase is used to break down alginate or alginic acid and to reduce viscosity. It is useful during follicle isolation, encapsulation, and culture .
Alginate Lyase has been used:
- in the pre-processing of enzyme
- to de-encapsulate cells
- to digest Pseudomonas exopolysaccharide to facilitate electroporation
Biochem/physiol Actions
Breaks down alginate or alginic acid to smaller molecules and reduces viscosity.
Alginate lyases actively participates in the saccharification of the acidic polysaccharides for the production of bioethanol.
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.
Other Notes
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

can you tell me PKa value of the Alginate lyase enzyme

I read on your site, that Alginat lyase should be resuspended at a concentration of 0.05 - 1.5 u/ml in 0.1 mol/L Phosphate buffer (pH 6.3). What if I prepared 24 U/ml (1mg contains 24U). Can this be harmful for the sample?
1 answer-
At high concentrations, Alginate lyase may degrade the entire extracellular matrix too rapidly and damage the structural integrity of encapsulated cells or tissue constructs. It may also cause unwanted aggregation or precipitation of breakdown products, and the high protein concentration itself might interfere with downstream applications.

Hi, is this enzyme a G-lyase (specific for GG-linkages) or M-lyase (specific for MM-linkages)?
1 answer-
This enzyme degrades GG linkages approximately twice as effectively as MM linkages.

I was wondering how to prepare the enzyme solution and what does the 1 un/ml mean? Is is 1 unit/mL or what does the un stand for? How do I convert the units to grams?
1 answer-
A1603 should be resuspended at a concentration of 0.05 - 1.5 u/ml in 0.1 mol/L Phosphate buffer (pH 6.3).
The specific activity of each lot (units/gram solid) is provided on the certificate of analysis. The lot specific certificate of analysis can be found here:
https://www.sigmaaldrich.com/product/sigma/a1603#product-documentation
Based on the specific activity (units/gram solid), the researcher can weigh out the appropriate amount of A1603 to achieve a 1 unit/mL solution.

I ordered the alginate lyase from your company. But the information that I received only present >=10,000U/g. And I need the 20U/m in my experiment. Could you give me more information?
1 answer-
The exact specific activity value is specified on the lot specific Certificate of Analysis. Please see this example Certificate of Analysis: https://www.sigmaaldrich.com/certificates/sapfs/PROD/sap/certificate_pdfs/COFA/Q14/A1603-BULKSLCQ2940.pdf.
