    "CsrC RNA binds to and probably sequesters CsrA, thereby inhibiting CsrA activity (Weilbacher T,2003). SraK is reported to be a small RNA of approximately 245 nt in length (Argaman L,2001), Tpk2 is reported to be a small RNA of 250 nt in length (Rivas E,2001), and RyiB/CsrC is reported to be a small RNA of approximately 270 nt in length (Wassarman KM,2001). SraK and RyiB are reported to be the same RNA (Gottesman S,2001). The IS198 gene is reported (by (Chen S,2002)) to encode a 13 residue peptide but also to be the same as the gene encoding .....
