Conserved protein; Catalyzes the hydrolysis of alpha,alpha-trehalose into two molecules of D-glucose.

Trehalose synthase TreS; Catalyzes the reversible interconversion of maltose and trehalose by transglucosylation. Also displays amylase activity, catalyzing the endohydrolysis of (1->4)-alpha-D- glucosidic linkages in glycogen and maltooligosaccharides such as maltoheptaose, to produce maltose which then can be converted to trehalose. TreS plays a key role in the utilization of trehalose for the production of glycogen and alpha-glucan via the TreS-Pep2 branch involved in the biosynthesis of maltose-1-phosphate (M1P). Might also function as a sensor and/or regulator of trehalose levels [...]

60 kDa chaperonin 2; Prevents aggregation of substrate proteins and promotes their refolding.

Two component transcriptional regulatory protein DevR (probably LuxR/UhpA-family); Member of the two-component regulatory system DevR/DevS (also called DosR/DosS) involved in onset of the dormancy response.
