Protein
Alpha,alpha-trehalose-phosphate synthase [UDP-forming]
Gene
otsA, SPAB_01230
Organism
Salmonella paratyphi B (strain ATCC BAA-1250 / SPB7)
Status
Reviewed - 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.

Catalytic activityi

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