“…A similar IR sequence has been found upstream from the promoters of csrB and csrC and of rsmB, rsmX, rsmY, and rsmZ genes from different gammaproteobacteria, which are regulated by BarA/SirA orthologous (31)(32)(33)(34)(35)(36)(37)(38)(39)(40). Moreover, a computational sequence analysis, including a wide number of characterized and predicted csrB, csrC, rsmB, rsmX, rsmY, and rsmZ genes revealed some differences between the IR sequences of csrB (TGTGAGAG ATCTCTTACA), csrC (TGTGAGNCATNGNCCATN), and rsmX, rsmY, and rsmZ (TGTAAGNNATNGCTTACA) genes (36).…”
