CC   -!- FUNCTION: Catalyzes the depolymerization of alginate by cleaving the
CC       beta-1,4 glycosidic bond between two adjacent sugar residues via a
CC       beta-elimination mechanism. May serve to degrade mislocalized alginate
CC       that is trapped in the periplasmic space. {ECO:0000255|HAMAP-
CC       Rule:MF_00557}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Eliminative cleavage of alginate to give oligosaccharides with
CC         4-deoxy-alpha-L-erythro-hex-4-enuronosyl groups at their non-reducing
CC         ends and beta-D-mannuronate at their reducing end.; EC=4.2.2.3;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00557};
CC   -!- SUBCELLULAR LOCATION: Periplasm {ECO:0000255|HAMAP-Rule:MF_00557}.
CC   -!- SIMILARITY: Belongs to the polysaccharide lyase 5 family.
CC       {ECO:0000255|HAMAP-Rule:MF_00557}.
