Structural Basis of Thermostability

Structural basis of thermostability. Analysis of stabilizing mutations in subtilisin BPN'.

The crystal structures of two thermally stabilized subtilisin BPN' variants, S63 and S88, are reported here at 1.8 and 1.9 A resolution, respectively. The micromolar affinity calcium binding site (site A) has been deleted (Delta75-83) in these variants, enabling the activity and thermostability measurements in chelating conditions. Each of the variants includes mutations known previously to inc...

Structural Basis for Thermostability of -Glycosidase from the Thermophilic Eubacterium Thermus nonproteolyticus HG102

Structural basis for thermostability of beta-glycosidase from the thermophilic eubacterium Thermus nonproteolyticus HG102.

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 re...

Molecular basis for the thermostability of Newcastle disease virus

Thermostable Newcastle disease virus (NDV) vaccines have been used widely to protect village chickens against Newcastle disease, due to their decreased dependence on cold chain for transport and storage. However, the genetic basis underlying the NDV thermostability is poorly understood. In this study, we generated chimeric viruses by exchanging viral genes between the thermostable TS09-C strain...
