Promoter pCadC

pCadC is a pH-sensitive promoter, designed to response the low-pH conditions.

Usage and Biology

pCadC is regulated by membrane-tethered activator protein (CadC), exhibits higher activity in acidic media than in media at neutral pH. In pH reporter strains, it’s used to test their response to acidic conditions in tumors induction.

Characterization

pH induced promoter testing

We constructed a pH reporter consisting of the pH-inducible promoter pCadC+mRFP. To test itsperformance, we added reporter in different chassis organisms. Fig 1,2 illustrates that pCadC induces the expression of the downstream gene mRFP with the decrease of pH,. Thus, it can be seen that pH reporter can work properly.
