κ-Carrageenase (EC 3.2.1.83, κ-carrageenan 4-β-D-glycanohydrolase) is an enzyme with systematic name κ-carrageenan 4-β-D-glycanohydrolase (configuration-retaining).[1][2][3][4][5] It catalyses the endohydrolysis of (1→4)-β-D-linkages between D-galactose 4-sulfate and 3,6-anhydro-D-galactose in κ-carrageenans
The main products of hydrolysis are neocarrabiose-sulfate and neocarratetraose-sulfate.
