Ionic network at the C-terminus of the beta-glycosidase from the hyperthermophilic archaeon Sulfolobus solfataricus: Functional role in the quaternary structure thermal stabilization.

Abstract excerpt

Biochemical, crystallographic, and computational data support the hypothesis that electrostatic interactions are among the dominant forces in stabilizing hyperthermophilic proteins. The thermostable beta-glycosidase from the hyperthermophile Sulfolobus solfataricus (Ssbeta-gly) is an interesting model system for the study of protein adaptation to high temperatures. The largest ion-pair network of Ssbeta-gly is...
