Protein name

RecName: Full=Alginate lyase; EC=4.2.2.3; AltName: Full=Poly(beta-D-mannuronate) lyase; AltName: Full=Poly(mana) alginate lyase; Flags: Precursor;

Gene name

algL

FUNCTION: Depolymerizes alginate by cleaving the beta-1,4 glycosidic bond (By similarity).

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.

SUBCELLULAR LOCATION: Periplasm (Potential).

SIMILARITY: Belongs to the polysaccharide lyase 5 family.
