Function

Depolymerizes alginate by cleaving the beta-1,4 glycosidic bond By similarity. HAMAP-Rule MF_00557

Catalytic activity

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. HAMAP-Rule MF_00557

Subcellular location

Periplasm By similarity.

Sequence similarities

Belongs to the polysaccharide lyase 5 family.
