The SraB RNA is a small
non-coding RNA discovered in ''
E. coli
''Escherichia coli'' (),Wells, J. C. (2000) Longman Pronunciation Dictionary. Harlow ngland Pearson Education Ltd. also known as ''E. coli'' (), is a Gram-negative, facultative anaerobic, rod-shaped, coliform bacterium of the genus ''Escher ...
'' during a large scale experimental screen.
The 14 novel RNAs discovered were named 'sra' for small RNA, examples include
SraC,
SraD and
SraG.
This ncRNA was found to be expressed only in
stationary phase.
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
Ovalbumin (abbreviated OVA) is the main protein found in egg white, making up approximately 55% of the total protein. Ovalbumin displays sequence and three-dimensional homology to the serpin superfamily, but unlike most serpins it is not a serine ...
.
The authors suggest this may be due to SraB regulating a response to components in albumin.
