Protein attributes

Sequence length	367 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Depolymerizes alginate by cleaving the beta-1,4 glycosidic bond. May enhance the production of alginate by controlling the length of the polymer chain during export. HAMAP 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 ends. HAMAP MF_00557
Subcellular location	Periplasm HAMAP MF_00557.
Sequence similarities	Belongs to the polysaccharide lyase 5 family.
