[1] Expression of SraD is highly abundant in stationary phase, but low levels could be detected in exponentially growing cells as well.

This RNA binds the Hfq protein and regulates levels of gene expression by an antisense mechanism.

MicA is known to interact with the mRNA encoding the quorum sensing synthase homolog, LuxS in E.coli and both RNAs are processed by the double stranded RNA endonuclease, RNase III.

[6] Based on its conservation, this is presumably the case in close relatives and may serve as a long elusive link between envelope stress and quorum sensing.

This links micA to cellular processes such as Mg(2+) transport, virulence, LPS modifications and resistance to antimicrobial peptides.
