S. dysenteriae encodes for two nearly identical RyfA molecules, sibling small regulatory RNAs (sRNAs) here designated RyfA1 and RyfA2. RyfA1 and RyfA2 represent putative sibling sRNAs 95% identical to one another and with greater than 90% nucleic acid identity to the singlet RyfA encoded at the same chromosomal location in all other species of Shigella as well as several isolates of E. coli.
