Lac promoter

Part Description

A CAP binding site and the lac operator sequence lacO are present in this lac promoter. Although the lac promoter is not as potent as the tac or trc promoters, it nevertheless provides for decent quantities of foreign protein production in high copy-number vectors. Expression from the lac promoter is activated in the absence of the lac repressor (LacI).

Usage

We use the lac promoter as a constitutive promoter for the regulation of (Phenylalanine-specific permease)expression even if it is not as powerful as the tac or trc promoters.it still showing significant levels of phenylalanine enough to induce and start our circuit activity by improving the permeability of the membrane to phenylalanine as shown in figure 1.
