These results are consistent with the role of FimW as a negative regulator of fimbrial expression , acting either directly on the fimA promoter to indirectly through the activity of other regulatory molecules .
These results are consistent with the role of FimW as a negative regulator of fimbrial expression , acting either directly on the fimA promoter to repress transcription .
that the regulatory effect of FimW is not due to the binding of FimW alone at the fimA promoter
These results demonstrate that the fimZ gene encodes a positive regulator for fimA , while FimW is a repressor for fimA .
