Catalyzes the depolymerization of alginate by cleaving the beta-1,4 glycosidic bond between two adjacent sugar residues via a beta-elimination mechanism. Degrades deacetylated polymannuronate (polyM) alginate from P.aeruginosa more efficiently than non-deacetylated polyM and alginate from M.pyrifera. AlgL from P.syringae degrades also its own alginate, which may indicate a role in cleaving preformed alginate and/or in determining the length of the alginate polymer (PubMed:11029455). May serve to degrade mislocalized alginate that is trapped in the periplasmic space (By similarity).

Belongs to the polysaccharide lyase 5 family.
