In enzymology a poly(beta-D-mannuronate) lyase (EC 4.2.2.3) is an enzyme that catalyzes the chemical reactionEliminative cleavage of polysaccharides containing beta-D-mannuronate residues to give oligosaccharides with 4-deoxy-alpha-L-erythro-hex-4-enopyranuronosyl groups at their endsThis 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-14-mannuronide) lyase.
