| Accepted Name |
|---|
| Poly(beta-D-mannuronate) lyase.
|
| Alternative Name(s) |
|---|
| Alginate lyase I. |
| Poly(mana) alginate lyase. |
| Reaction catalysed |
|---|
| Eliminative cleavage of polysaccharides containing beta-D-mannuronate residues to give oligosaccharides with 4-deoxy-alpha-L-erythro-hex-4-enopyranuronosyl groups at their non-reducing ends |
| Comment(s) |
|---|
- The enzyme from the bacterium Sphingomonas sp. strain A1 cleaves
