\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** .
