EC | 3.2.1.83 | ||||||||||
Accepted name: | κ-carrageenase | ||||||||||

Glossary: | In the field of oligosaccharides derived from agarose, carrageenans, etc., in which alternate residues are 3,6-anhydro sugars, the prefix ’neo’ designates an oligosaccharide whose non-reducing end is the anhydro sugar, and the absence of this prefix means that it is not. For example: ι-neocarrabiose = 3,6-anhydro-2-O-sulfo-α-D-galactopyranosyl-(1→3)-4-O-sulfo-D-galactose ι-carrabiose = 4-O-sulfo- β-D-galactopyranosyl-(1→4)-3,6-anhydro-2-O-sulfo-D-galactose |

Other name(s): | κ-carrageenan 4-β-D-glycanohydrolase | ||||||||||
Systematic name: | κ-carrageenan 4-β-D-glycanohydrolase (configuration-retaining) | ||||||||||
Comments: | The main products of hydrolysis are neocarrabiose-sulfate and neocarratetraose-sulfate [5]. Unlike EC 3.2.1.157 (ι-carrageenase), but similar to EC 3.2.1.81 (β-agarase), this enzyme proceeds with retention of the anomeric configuration. | ||||||||||
