• PubMed Abstract: 
  

  The β-glucosidase A gene (bglA) has been cloned from the halothermophilic bacterium Halothermothrix orenii and the recombinant enzyme (BglA; EC 3.2.1.21) was bacterially expressed, purified using metal ion-affinity chromatography and subsequently crystallized. Orthorhombic crystals were obtained that diffracted to a resolution limit of 3.5 Å. The crystal structure with two molecules in the asymmetric unit was solved by molecular replacement using a library of known glucosidase structures. Attempts to collect higher resolution diffraction data from crystals grown under different conditions and structure refinement are currently in progress.
