Substrate specificities
The glycoside hydrolases of this family are endo-acting α-fucosidases active on sulfated fucans (or fucoidans) from brown algae.
All described GH107 family members are endo-1,4-fucanase of bacterial origin.
With enzymes from the CAZY family GH29 they form the clan GH-R.
Kinetics and Mechanism
Content is to be added here.
Catalytic Residues
The catalytic nucleophile is an aspartate, while the catalytic acid-base is a histidine. The later is unusual in GHs, and a divergence from GH29, but is likely necessary to avoid electronic repulsion with the substrate sulfate groups.
Three-dimensional structures
Content is to be added here.
Family Firsts
- First stereochemistry determination

- First general acid/base residue identification
