Promoters and (their often forgotten partner-in-crime) operators are two key elements in the transcription of a protein sequence. A promoter sequence recruits the RNA polymerase and the status of the operator determines whether or not the adjunctive protein sequence gets translated (Figure 1). So far, biochemistry 101. Far more interesting is the diversity in promoter/operator complexes currently employed in the biotech industry and their associated efficiency rates. Not a lot of quantitative and real comparable research had been done on this topic, until March 2013…
