RtT RNA
The RtT RNA is a RNA element that is released from the tyrT operon of Escherichia coli. The exact function of RtT is unknown although it is thought that it may be involved in changing the cellular response in relation to amino acid starvation.
The functional prediction is strengthened when the tyrT locus of E. coli K12 is compared with the B strain, which lacks RtT RNA and has an alternate starvation response.
