IUBMB Comments
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 catalyses a beta-elimination reaction, generating a new unsaturated non-reducing end after removal of the pre-existing one.
