periplasmic sugar-binding domain of Thermotoga maritima glucose-binding protein (tmGBP) and its close homologs
Periplasmic sugar-binding domain of Thermotoga maritima glucose-binding protein (tmGBP) and its close homologs from other bacteria. They are members of the type 1 periplasmic binding protein superfamily which consists of two domains connected by a three-stranded hinge. TmGBP is specific for glucose and its binding pocket is buried at the interface of the two domains. TmGBP also exhibits high thermostability and the highest structural similarity to E. coli glucose binding protein (ecGBP).
