Comments Supplementary Text 2 p.23 top paragraph:"The synthesis rate of signal peptides in QS [quorum sensing] systems has not been measured. A typical transcription initiation rate (BNID 111997) of 20 min^-1 at a gene with an average mRNA half-life (primary sources) of 1 min, gives a steady state estimate of 30 mRNAs per cell."
