Heparinase I （EC 4.2.2.7） （ratio approx. 3:1）. Eliminative cleavage of polysaccharides containing 1,4-linked D-glucuronate or L-iduronate residues and 1,4-a-linked 2-sulfoamino-2-deoxy-6-sulfo-D-glucose residues to give oligosaccharides with terminal 4-deoxy-a-D-gluc-4-enuronosyl groups at their non-reducing ends Heparinase I cleaves heparin, and to a lesser extent, heparan sulfate. （MSDS Sheet）.

Heparinase II （EC unassigned） Heparinase II cleaves heparin and heparan sulfate.

Heparinase III （EC 4.2.2.8） Heparinase III cleaves heparan sulfate exclusively, and does not cleave unfractionated heparin or low molecular weight heparins.

Chondroitinase AC（EC 4.2.2.5） Eliminative degradation of polysaccharides containing 1,4-b-D-hexosaminyl and 1,3-b-D-glucuronosyl linkages to disaccharides containing 4-deoxy-b-D-gluc-4-enuronosyl groups. Chondroitinase AC cleaves chondroitin sulfates A and C.

Chondroitinase B （EC 4.2.2.19） Chondroitinase B cleaves dermatan sulfate.
