Cytoplasmic trehalase

Gene

treF

Organism
Salmonella newport (strain SL254)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Hydrolyzes trehalose to glucose. Could be involved, in cells returning to low osmolarity conditions, in the utilization of the accumulated cytoplasmic trehalose, which was synthesized in response to high osmolarity.UniRule annotation

Catalytic activityi

Alpha,alpha-trehalose + H2O = beta-D-glucose + alpha-D-glucose.UniRule annotation

Pathwayi: trehalose degradation

This protein is involved in step 1 of the subpathway that synthesizes D-glucose from alpha,alpha-trehalose.UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Cytoplasmic trehalase (treF)
This subpathway is part of the pathway trehalose degradation, which is itself part of Glycan degradation.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes D-glucose from alpha,alpha-trehalose, the pathway trehalose degradation and in Glycan degradation.

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.
