Gene

otsA

Organism
Salmonella arizonae (strain ATCC BAA-731 / CDC346-86 / RSK2980)
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.

Pathwayi: trehalose biosynthesis

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
