rdlD RNA is a family of small non-coding RNAs which repress the protein ldrD in a type I toxin-antitoxin system. It was discovered in Escherichia coli strain K-12 in a long direct repeat (LDR) named LDR-D. This locus encodes two products: a 35 amino acid peptide toxin (ldrD) and a 60 nucleotide RNA antitoxin. The toxin mRNA has a half-life of around 30 minutes while rdlD RNA has a half-life of only 2 minutes. This is in keeping with other type I toxin-antitoxin systems.
