Enzyme Information

4.2.2.26
Oligo-alginate lyase.
based on mapping to UniProt Q21FJ0
Cleavage of 4-deoxy-alpha-L-erythro-hex-4-enopyranuronoside oligosaccharides into 4-deoxy-alpha-L-erythro-hex-4-enopyranuronate monosaccharides.
-!- The enzyme degrades unsaturated oligosaccharides produced by the action of alginate lyases (EC 4.2.2.3 and EC 4.2.2.11) on alginate, by repeatedly removing the unsaturated residue from the non-reducing end until only unsaturated monosaccharides are left. -!- The enzyme catalyzes a beta-elimination reaction, generating a new unsaturated non-reducing end after removal of the pre-existing one.
