| Comments |
The main products of hydrolysis are ¦É-neocarratetraose sulfate and ¦É-neocarrahexaose sulfate. ¦É-Neocarraoctaose is the shortest substrate oligomer that can be cleaved. Unlike EC?3.2.1.81, ¦Â-agarase and EC?3.2.1.83, ¦Ê-carrageenase, this enzyme proceeds with inversion of the anomeric configuration. ¦É-Carrageenan differs from ¦Ê-carrageenan by possessing a sulfo group on O-2 of the 3,6-anhydro-D-galactose residues, in addition to that present in the ¦Ê-compound on O-4 of the?D-galactose residues. |
