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].
