Gel mobility retardation of tox promoters with C. difficile RNA polymerase and TxeR; gel mobility retardation of the C. difficile glutamate dehydrogenase gene promoter (Pgdh), toxin B gene promoter (PtoxB), and toxin A gene promoter (PtoxA) by C. difficile RNA polymerase. For gdh promoter, left lane is Pgdh DNA alone and right lane is Pgdh DNA incubated with C. difficile RNA polymerase. For toxB and toxA promoters, left lane is tox promoter DNA alone, middle lane is tox promoter DNA with C. difficile RNA polymerase, and right lane is tox promoter DNA with C. difficile RNA polymerase and TxeR, respectively.
