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.
