KEGG   ENZYME: 3.2.1.162
Entry
EC 3.2.1.162                Enzyme                                 
Name
lambda-carrageenase;
endo-beta-1,4-carrageenose 2,6,2'-trisulfate-hydrolase
Class
Hydrolases;
Glycosylases;
Glycosidases, i.e. enzymes that hydrolyse O- and S-glycosyl compounds
Sysname
endo-(1->4)-beta-carrageenose 2,6,2'-trisulfate-hydrolase
Reaction(IUBMB)
Endohydrolysis of (1->4)-beta-linkages in the backbone of lambda-carrageenan, resulting in the tetrasaccharide alpha-D-Galp2,6S2-(1->3)-beta-D-Galp2S-(1->4)-alpha-D-Galp2,6S2-(1->3)-D-Galp2S
Comment
The enzyme from Pseudoalteromonas sp. is specific for lambda-carrageenan. iota-Carrageenan (see EC 3.2.1.157, iota-carrageenase), kappa-carrageenan (see EC 3.2.1.83, kappa-carrageenase), agarose and porphyran are not substrates.
