Description
This enzyme sulfates the residues marked with an asterisk in sequences containing at least → IdoA2S→ GlcN*→ or → GlcA2S→ GlcN*→ (symbols as in 2-Carb-38). Preference for GlcN2S vs. unmodified GlcN has not yet been established. Additional structural features are presumably required for substrate recognition, since the 3-O-sulfated residue is of low abundance, whereas the above IdoA-containing sequence is quite abundant. This enzyme differs from the other [heparan sulfate]-glucosamine 3-sulfotransferases by modifying selected glucosamine residues preceded by GlcA2S; EC 2.8.2.23 ([heparan sulfate]-glucosamine 3-sulfotransferase 1) prefers GlcA or IdoA, whereas EC 2.8.2.30 ([heparan sulfate]-glucosamine 3-sulfotransferase 3) prefers IdoA2S.
