abstract：:The small noncoding RNA RyhB is a regulator of iron homeostasis in Escherichia coli. During iron limitation, it downregulates the expression of a number of iron-containing proteins, including enzymes of the tricarboxylic acid cycle and the respiratory chain. Because this infers a potential for RyhB to limit energy met...
