Protein
Ectoine/5-hydroxyectoine-binding periplasmic protein UehA
Organism
Ruegeria pomeroyi (strain ATCC 700808 / DSM 15171 / DSS-3)
Function
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.
Similarity
Belongs to the bacterial solute-binding protein 7 family.
