abstract：:Noncoding RNA regulators have been implicated in almost all imaginable cellular processes. Here we review how regulatory small RNAs such as Spot42, SgrS, GlmY, and GlmZ and a cis-encoded ribozyme in glmS mRNA control sugar metabolism. Besides discussing the physiological implications, we show how the study of these mo...
