heparanase promotes the activity of this mitogenic protein by removing the heparan sulfate chains from syndecan-1 leaving the deglycanated heparan sulfate proteoglycans as the active receptor for lacritin |

3.2.1.166 | [GlcAbeta(1,4)GlcNSO3H-3SO3Halpha(1,4)]m-GlcAbeta(1,4)GlcNSO3H-3SO3Halpha(1,4)-[GlcAbeta(1,4)GlcNSO3H-3SO3H]n + H2O |
both N- and O-sulfations (either 6-O-sulfation or 3-O-sulfation) are required for the cleavage by heparanase. Structural moiety recognized by heparanase includes a GlcA unit and GlcNS unit carrying O-sulfations. The enzyme proves to be promiscuous in the aspect of the type and location of O-sulfation required for recognition |

heparanase does not cleave the linkage of GlcA2S-GlcNS but rather cleaves the linkage of GlcA-GlcNS nearby |
