CAS Number: 9024-15-1
MDL Number: MFCD03454593
Product Type: Chemical
Alginate lyase specificity: Alginic acid is composed of of blocks of β-D-(1-4) mannuronic acid homopolymeric regions (MMMM…), α-L-(1-4)-guluronic acid (GGGG…) homopolymeric regions, and alternating copolymer regions of β-D-(1-4) mannuronic acid - α-L-(1-4)-guluronic acid (GMGMGM…). Bacterial alginic acid can be acetlylated at the 2 or 3 positions on mannuronic acid.

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