This non-coding RNA was discovered in the bacteria Escherichia coli during a large scale computational screen for transcription signals and genomic features of known small RNA-encoding genes. During this screen 14 novel ncRNA genes were identified, including GlmZ, SraB, SraC and  SraD.
A previously unknown type of RNA was discovered in the bacteria Escherichia coli through a large-scale computational analysis aimed at identifying transcriptional signals and genomic features associated with small RNAs. This study uncovered 14 novel non-coding RNA genes, including GlmZ, SraB, SraC, and SraD.
