Enzyme Information
| 2.8.2.23 | [Heparan sulfate]-glucosamine 3-sulfotransferase 1. based on mapping to UniProt O35310 3'-phosphoadenylyl sulfate + [heparan sulfate]-glucosamine = adenosine 3',5'-bisphosphate + [heparan sulfate]-glucosamine 3-sulfate. -!- This enzyme differs from EC 2.8.2.29 and EC 2.8.2.30 by being the most selective for a precursor of the antithrombin-binding site. -!- It has a minimal acceptor sequence of: -> GlcNAc6S->GlcA-> GlcN2S*+-6S->IdoA2S->GlcN2S->. -!- It can also modify other precursor sequences within heparan sulfate but this action does not create functional antithrombin-binding sites. -!- These precursors are variants of the consensus sequence: -> Glc(N2S>NAc)+-6S->GlcA->GlcN2S*+-6S->GlcA>IdoA+-2S-> Glc(N2S/NAc)+-6S->. -!- If the heparan sulfate substrate lacks 2-O-sulfation of GlcA residues, then enzyme specificity is expanded to modify selected glucosamine residues preceded by IdoA as well as GlcA. |
