C0343 RNA

The C0343 RNA is a bacterial non-coding RNA of 74 nucleotides in length that is found between the ydaN and dbpA genes in the genomes of Escherichia coli and Shigella flexneri, Salmonella enterica and Salmonella typhimurium. This ncRNA was originally identified in E.coli using high-density oligonucleotide probe arrays (microarray). The function of this ncRNA is unknown.

FnrS RNA was later found to be transcribed from the same intergenic region as C0343 RNA.
