The SraB RNA is a small non-coding RNA discovered in E. coli during a large scale experimental screen.[1] The 14 novel RNAs discovered were named 'sra' for small RNA, examples include SraC, SraD and SraG.[1] This ncRNA was found to be expressed only in stationary phase.[1] The exact function of this RNA is unknown but it has been shown to affect survival of Salmonella enterica to antibiotic administration in egg albumin.[2] The authors suggest this may be due to SraB regulating a response to components in albumin.
