The structure of a family 168 glycoside hydrolase from the marine bacterium Muricauda eckloniae

Acta Crystallographica Section F, Volume 81, Issue 7, Page 281-286, July 2025.
The structure of a putative fucoidan‐degrading glycoside hydrolase assigned to glycoside hydrolase family 168 reveals a (β/α)8 fold. The catalytic machinery and potential substrate specificity were investigated through a structural comparison with a Fun168A oligosaccharide complex.The genome of the marine bacterium Muricauda eckloniae sp.

Carbohydrates of the brown seaweeds Desmarestia firma and Dictyopteris plagiogramma and of the diatom Coscinodiscus nobilis [PDF]

, 1980
Dictyopteris plagiogramma: The carbohydrates of this weed have been chemically studied for the first time. Sequential extraction of the weed gave a mixture of laminaran and 'fucan' in the aqueous extract and a mixture of alginic acid and 'fucan' in the ...
