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