            "SraA is a small RNA of approximately 120 nt in length (Argaman L,2001). SraA RNA has similarity to sequences from Salmonella and Klebsiella pneumoniae (Argaman L,2001). Sra: small RNA (Argaman L,2001). PsrA: predicted small RNA (Argaman L,2001). Regulation has been described (Argaman L,2001). Reviews: (Gottesman S,2001. Hershberg R,2003). "
