Crystal structure of thermostable beta-glycosidase from thermophilic eubacterium Thermus nonproteolyticus HG102
OverviewOverview
The three-dimensional structure of a thermostable beta-glycosidase (Gly(Tn)) from the thermophilic eubacterium Thermus nonproteolyticus HG102 was determined at a resolution of 2.4 A. The core of the structure adopts the (betaalpha)(8) barrel fold. The sequence alignments and the positions of the two Glu residues in the active center indicate that Gly(Tn) belongs to the glycosyl hydrolases of retaining family 1. We have analyzed the structural features of Gly(Tn) related to the thermostability and compared its structure with those of other mesophilic glycosidases from plants, eubacteria, and hyperthermophilic enzymes from archaea. Several possible features contributing to the thermostability of Gly(Tn) were elucidated.
