Enzyme Information

3.2.1.83

Kappa-carrageenase.

based on mapping to UniProt P43478

Endohydrolysis of (1->4)-beta-D-linkages between D-galactose 4-sulfate and 3,6-anhydro-D-galactose in kappa-carrageenans.

-!- The main products of hydrolysis are neocarrabiose-sulfate and neocarratetraose-sulfate. -!- Unlike EC 3.2.1.157, but similar to EC 3.2.1.81, this enzyme proceeds with retention of the anomeric configuration.
