The crystal structure of acidic β-galactosidase from Aspergillus oryzae.

The crystal structure of the industrially important Aspergillus oryzae β-galactosidase has been determined at 2.60 Å resolution. The Ao-β-gal is a large (985 residues) monomeric multi-domain enzyme that has a catalytic (α/β)8-barrel domain.
