The carbon storage regulatory (Csr) system is a complex network controlling various phenotypes in many eubacteria. So far, the external conditions by which the system is regulated are poorly understood. Here we show that the expression of the two noncoding small RNAs CsrB and CsrC in Escherichia coli is strongly increased in cultures grown in minimal medium. Addition of tryptone, casamino acids or a mixture of amino acids to a culture grown in minimal medium led to a rapid reduction in the… CONTINUE READING
