General annotation (Comments)

Function	Regulatory subunit of the trehalose synthase complex that catalyzes the production of trehalose from glucose-6-phosphate and UDP-glucose in a two step process. May stabilize the trehalose synthase complex, and confer sensitivity to physiological concentrations of phosphate and to fructose 6-phosphate. Ref.3
Subunit structure	The trehalose synthase complex is composed of the two catalytic subunits TPS1 and TPS2, and at least one of the two regulatory subunits TPS3 or TSL1. Ref.4
Subcellular location	Cytoplasm.
Induction	Repressed by glucose.
Domain	C-terminal 700 AA are mainly in alpha-helices and beta-sheets.
Miscellaneous	Present with 1960 molecules/cell in log phase SD medium. Ref.7
Sequence similarities	In the C-terminal section; belongs to the glycosyltransferase 20 family.
