Term Name:	poly(alpha-L-guluronate) lyase activity
Synonyms:	alginase II activity, guluronate lyase activity, L-guluronan lyase activity, L-guluronate lyase activity, poly(alpha-L-1,4-guluronide) exo-lyase activity, poly-alpha-L-guluronate lyase activity, polyguluronate-specific alginate lyase activity
Definition:	Catalysis of the reaction: polysaccharides containing a terminal alpha-L-guluronate group = oligosaccharides with 4-deoxy-alpha-L-erythro-hex-4-enuronosyl end. This reaction is the eliminative cleavage of polysaccharides containing a terminal a-L-guluronate group, to give oligopolysaccharides with 4-deoxy-a-L-erythro-hex-4-enuronosyl groups at their nonreducing ends.
