alpha,alpha-trehalose-phosphate synthase complex (UDP-forming)

id: GO:0005946
name: alpha,alpha-trehalose-phosphate synthase complex (UDP-forming)
namespace: cellular_component
type: go
obsolete: False

Description: A protein complex that possesses alpha,alpha-trehalose-phosphate synthase (UDP-forming) and trehalose-phosphatase activities, and thus catalyzes two reactions in trehalose biosynthesis. In the complex identified in Saccharomyces, Tps1p has alpha,alpha-trehalose-phosphate synthase (UDP-forming) activity, Tps2p has trehalose 6-phosphate phosphatase activity; Tps3p is a regulatory subunit, and an additional subunit, Tsl1p, may be present.
