ENZYME entry: EC 3.2.1.157
| Accepted Name |
|---|
| Iota-carrageenase.
|
| Reaction catalysed |
|---|
| Endohydrolysis of 1,4-beta-D-linkages between D-galactose 4-sulfate and 3,6-anhydro-D-galactose-2-sulfate in iota-carrageenans |
| Comment(s) |
|---|
- 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 and EC 3.2.1.83, 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.
