EC 3.2.1.162 Details
EC number
3.2.1.162
Accepted name
λ-carrageenase
Reaction
Endohydrolysis of (1→4)-β-linkages in the backbone of λ-carrageenan, resulting in the tetrasaccharide α-D-Galp2,6S2-(1→3)-β-D-Galp2S-(1→4)-α-D-Galp2,6S2-(1→3)-D-Galp2S
Other name(s)
endo-β-1,4-carrageenose 2,6,2′-trisulfate-hydrolase
Systematic name
endo-(1→4)-β-carrageenose 2,6,2′-trisulfate-hydrolase
Comment
The enzyme from Pseudoalteromonas sp. is specific for λ-carrageenan. ι-Carrageenan (see EC 3.2.1.157, ι-carrageenase), κ-carrageenan (see EC 3.2.1.83, κ-carrageenase), agarose and porphyran are not substrates.
