Enzyme Information

4.2.2.8	Heparin-sulfate lyase. based on mapping to UniProt C6XZB6 Elimination of sulfate, appears to act on linkages between N-acetyl-D- glucosamine and uronate. Product is an unsaturated sugar. -!- Does not act on N,O-desulfated glucosamine or N-acetyl-O-sulfated glucosamine linkages.
4.2.2.7	Heparin lyase. based on mapping to UniProt C6XZB6 Eliminative cleavage of polysaccharides containing (1->4)-linked D-glucuronate or L-iduronate residues and (1->4)-alpha-linked 2-sulfoamino-2-deoxy-6-sulfo-D-glucose residues to give oligosaccharides with terminal 4-deoxy-alpha-D-gluc-4-enuronosyl groups at their non- reducing ends.
