Right Regulatory Elements position in natural cI genetic switch

Lambda Fage Genetic switch is a complex and deeply characterized system. A Review on the natural systems behavior

ΔG of cI Binding to it's different operator sites and resulting Biological repression strength expressed as reduction in LacZ Activity

K079041: Lambda OR1 is the most affine wild type operator sequence in the Lambda system. In the natural switch overlaps with Cro Promoter PR.

K079042: Lambda OR2 is located upstream of OR1 partially overlapping the PR promoter. cI binding affinity for the operator sequence is significantly lower than OR1 (Higher Free Energy)

K079043: Lambda OR3 recruits cI with interaction energy comparable to OR2. The different biological role in the switch systems is related to positional effects being farther from PR sequence and overlapping cI promoter P.
