WebIt inhibits the lac promoter that transcribes T7 RNA polymerase which binds to the T7 promoter of the plasmid to initiate transcription of the dLDH gene. The lac repressor binds to both promoters and are induced by the same ligand: IPTG. Since both repressors are affected by IPTG, this controls the expression of the dLDH gene.
