Gal repressosome contains an antiparallel DNA loop.

Nature structural biology - 1 May 2001

Geanacopoulos M, Vasmatzis G, Zhurkin V B, Adhya S

Abstract excerpt

Gal repressosome assembly and repression of the gal operon in Escherichia coli occurs when two dimeric GalR proteins and the histone-like HU protein bind to cognate sites causing DNA looping. Structure-based genetic analysis defined the GalR surfaces interacting to form a stacked, V-shaped, tetra...
