Modeling: PoPS

From de article: "Measuring the activity of BioBrick promoters using an in vivo reference standard"

  • Promoter activity. Number of RNAp molecules that pass by the final base pair of the promoter and continue along DNA as an elongation complex.
  • PoPs (Absolute activity of promoter). Rate of successful mRNA initiation events per DNA copy of each promoter. Number of elongating polymerases per second (PoPs) exiting the promoter.
  • RPUs (Relative activity of promoter). Ratio of absolute activity of the promoter to the absolute activity of a reference standard promoter measure under the same conditions and with the same measurement instruments.
