Substrate specificities
Glycoside Hydrolases of family 55 exclusively consists of β-1,3-glucanases, including both exo- and endo-enzymes, at this moment.
Kinetics and Mechanism
Catalytic Residues
Three-dimensional structures
Two tandem β-helix domains positioned side by side. The active site is located between them.
Family Firsts
- First sterochemistry determination
- Cite some reference here, with a short explanation.
- First catalytic nucleophile identification
- First general acid/base residue identification
- First 3-D structure
- β-1,3-glucanase Lam55A from Phanerochaete chrysosporium K-3 by X-ray crystallography (PDB 3eqn and PDB 3eqo) [1].
