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
This enzyme belongs to the family of lyases, specifically those carbon-oxygen lyases acting on polysaccharides. The systematic name of this enzyme class is poly(beta-D-1,4-mannuronide) lyase. Other names in common use include alginate lyase I, alginate lyase, alginase I, alginase II, and alginase. This enzyme participates in fructose and mannose metabolism.
