ENZYME entry: EC 2.8.2.29

PURL: https://purl.expasy.org/enzyme/EC/2.8.2.29
Accepted Name
[heparan sulfate]-glucosamine 3-sulfotransferase 2
Alternative Name(s)
3-OST-2
glucosaminyl 3-O-sulfotransferase 2
heparan sulfate D-glucosaminyl 3-O-sulfotransferase 2
Reaction catalysed
alpha-D-glucosaminyl-[heparan sulfate](n) + 3'-phosphoadenylyl sulfate = 3-sulfo-alpha-D-glucosaminyl-[heparan sulfate](n) + adenosine 3',5'-bisphosphate + H(+)
Comment(s)
  • This enzyme sulfates the residues marked with an asterisk in sequences containing at least ->IdoA2S->GlcN*-> or ->GlcA2S->GlcN*->.
  • Preference for GlcN2S versus 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 prefers GlcA or IdoA, whereas EC 2.8.2.30 prefers IdoA2S.
