A fourth copy of CsrB in V. splendidus. (A) Visualization of the genomic context of CsrB2 (left) and CsrB4 (right) on the Artemis viewer. A graph representing the ln of the coverage is visible on the top window. Bam reads are visible below. (Salmon) The extent of both CsrBs. (Blue arrows) The two possible sizes of CsrB2. (Yellow boxes) Putative transcription terminator as predicted by ARNold. (B) Expression of the four CsrBs during growth of V. splendidus. The Northern blots were carried out as described in Figure 4. (C) Secondary structure of the four CsrBs as predicted by Mfold (see Materials and Methods for details). (Orange) The loops containing the CsrA binding motifs (AGGA or AGGGA).
