\frac{d[mRNAOxyR]}{dt}=PoPSconstitutive\times\frac{N}{V}-KdegmRNA[mRNAOxyR]

In this equation, PoPSconstitutive represents the promoter strength of promoter J23102, which is measured by the rate of RNApolymerase binding to the starting site of DNA transcription.

For the section of the equation, PoPSconstitutive\times\frac{N}{V} represents the synthesizing rate of mRNAOxyR ; -KdegmRNA[mRNAOxyR] represents the degrading rate of mRNAOxyR .
