Enzyme Information
| 4.2.2.3 |
Mannuronate-specific alginate lyase.
based on mapping to UniProt Q06749
Eliminative cleavage of alginate to give oligosaccharides with 4-deoxy- alpha-L-erythro-hex-4-enuronosyl groups at their non-reducing ends and beta-D-mannuronate at their reducing end.
-!- The enzyme catalyzes the degradation of alginate by a beta- elimination reaction. -!- It cleaves the (1->4) bond between beta-D-mannuronate and either alpha-L-guluronate or beta-D-mannuronate, generating oligosaccharides with 4-deoxy-alpha-L-erythro-hex-4-enuronosyl groups at their non- reducing ends and beta-D-mannuronate at the reducing end. -!- Depending on the composition of the substrate, the enzyme produces oligosaccharides ranging from two to four residues, with preference for shorter products. -!- Cf. EC 4.2.2.11. -!- Formerly EC 4.2.99.4.
