In vitro repression of the gal promoters by GalR and HU depends on the proper helical phasing of the two operators.

The Journal of biological chemistry - 25 Jan 2002

Lewis Dale E A, Adhya Sankar

Abstract excerpt

Repression of transcription initiation from the two gal promoters, P1 and P2, requires binding of GalR protein to two flanking operators, O(E) and O(I), binding of HU to a site, hbs, located between the two operators, and supercoiled DNA template. Previous experiments suggested that repression in...
