Figure 2

Distinguishing competition versus non-competition of transcription factors at promoter level in a chosen circuit architecture. Three different implementations compatible with the scheme in (A): Design I - inhibition through competition at the activator promoter (B), Design II -inhibition through active degradation of the activator by the repressor (C), and Design III - specific inhibition (d). The cases (B) and (C) are discussed in [18], while there is controversy whether the Atkinson oscillator [6] is based on case (B) [18] or (D) [44].
