spinqualitylabelsall models Structure o phage 434 repressor cI protein complex with DNA (PDB entry 1per) Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image   Print3D The bacteriophage repressor controls the genetic switch determining the lytic cycle following phage infection. It competes with the Cro protein which selects for the lysogenic cycle. Phage 434 repressor cI protein with DNA operator site OR3 (1per). For details see Lambda repressor.
