Protein

Trehalose-6-phosphate synthase

Gene

otsA

Organism
Mycobacterium leprae (strain TN)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Probably involved in the osmoprotection via the biosynthesis of trehalose and in the production of glycogen and alpha-glucan via the TreS-Pep2 branch involved in the biosynthesis of maltose-1-phosphate (M1P). Catalyzes the transfer of glucose from UDP-glucose (UDP-Glc) to D-glucose 6-phosphate (Glc-6-P) to form trehalose-6-phosphate. Probably also able to use ADP-Glc, CDP-Glc, GDP-Glc and TDP-Glc as glucosyl donors.By similarity

Catalytic activityi

ADP-alpha-D-glucose + D-glucose 6-phosphate = ADP + alpha,alpha-trehalose 6-phosphate.By similarity
CDP-alpha-D-glucose + D-glucose 6-phosphate = CDP + alpha,alpha-trehalose 6-phosphate.By similarity
GDP-alpha-D-glucose + D-glucose 6-phosphate = GDP + alpha,alpha-trehalose 6-phosphate.By similarity
TDP-alpha-D-glucose + D-glucose 6-phosphate = TDP + alpha,alpha-trehalose 6-phosphate.By similarity
UDP-alpha-D-glucose + D-glucose 6-phosphate = UDP + alpha,alpha-trehalose 6-phosphate.By similarity
