Protein

Ectoine/5-hydroxyectoine-binding periplasmic protein UehA

Gene

uehA

Organism
Ruegeria pomeroyi (strain ATCC 700808 / DSM 15171 / DSS-3) (Silicibacter pomeroyi)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Part of the tripartite ATP-independent periplasmic (TRAP) transport system UehABC, which imports both ectoine and 5-hydroxyectoine as nutrients, and not as osmoprotectants. UehA binds both ectoine and 5-hydroxyectoine with high specificity and affinity.1 Publication

Similar proteinsi

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.
