[back to top]

Salmonella LsrB binds a chemically distinct form of the AI-2 signal, (2R,4S)-2-methyl-2,3,3,4-tetrahydroxytetrahydrofuran (R-THMF), that lacks the boron found in Vibrio AI-2. LsrB is paralogous to ribose transport periplasmic binding protein RbsB and is in an operon regulated by LsrR and LuxS, through AI-2. otherPDB (S. typhimurium): 1TJY, 1TM2.^[4]
