Description
Py is the tra operon promoter of F-plasmid. It is repressed by the host nucleoid-associated protein, H-NS and activeted by TraJ protein. Conflicting evidence suggests that TraY can act as both an activator and a repressor. The tra operon encodes F-plasmid proteins (except TraJ and TraM) involved in DNA transfer by conjugation in E.coli. The regions shows intrinsic curvature, which could interfere in regulation. For this reason, the two closer bends upstream promoter region are included.
Notes
The mechanism for controlling transcription from Py remains undefined. The Py region contains significant intrinsic curvature, which could interfere in regulation
