Iota-carrageenase explained
| Iota-carrageenase |
| Ec Number: | 3.2.1.157 |
| Cas Number: | 50936-37-3 |
Iota-carrageenase is an enzyme with systematic name iota-carrageenan 4-beta-D-glycanohydrolase (configuration-inverting).[1] [2] [3] This enzyme catalyses the following chemical reaction
Endohydrolysis of (1->4)-beta-D-linkages between D-galactose 4-sulfate and 3,6-anhydro-D-galactose-2-sulfate in iota-carrageenans
The main products of hydrolysis are iota-neocarratetraose sulfate and iota-neocarrahexaose sulfate.
