Protein DNA Assemblies. (a) Structure of DNA binding domain and operator DNA (O^sym). (b) Wild-type operator DNA (O¹) and auxiliary operators O² and O³. O¹, O², O³, and O^sym all assemble with wild-type the DNA binding domain D¹. Variations of operator DNA (O^S2, O^S3, O^S4, and O^S5) assemble with orthogonal DNA binding domains (D^S2, D^S3, D^S4, and D^S5).
