laminarin

They use laminarin and mannitol for storage.

Substrates include laminarin, lichenin and cereal D-glucans.

It contains the storage polysaccharide laminarin and the tripeptide eisenin, a peptide with immunological activity.

The molecule laminarin (also known as laminaran) is a storage glucan (a polysaccharide of glucose) found in brown algae.

It is used as a carbohydrate food reserve by phytoplankton such as Bacillariophyta (similar to the use of laminarin by brown algae).

Other polysaccharides include callose or laminarin, chrysolaminarin, xylan, mannan, fucoidan, and galactomannan.

Other names in common use include laminarin phosphoryltransferase, 1,3-beta-D-glucan:orthophosphate glucosyltransferase, and laminarin phosphoryltransferase.

Both cleft A and cleft B can bind cello-oligosaccharides, laminarin preferentially binds in cleft A, xylooligosaccharides only bind in cleft A and beta1,4,-beta1,3-mixed linked glucans only bind in cleft B.
