Gene

otsA

Organism
Citrobacter koseri (strain ATCC BAA-895 / CDC 4225-83 / SGSC4696)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Catalyzes the transfer of glucose from UDP-glucose to glucose-6-phosphate to form alpha,alpha-1,1 trehalose-6-phosphate. Acts with retention of the anomeric configuration of the UDP-sugar donor (By similarity).By similarity

Catalytic activityi

UDP-glucose + D-glucose 6-phosphate = UDP + alpha,alpha-trehalose 6-phosphate.
