From: Integration of transcriptional inputs at promoters of the arabinose catabolic pathway
Simple mathematical model of promoter expression in arabinose regulon. The promoter, P, can be bound to AraC-arabinose (A*), CRP-cAMP (C*), or both. Transcription is theoretically possible in any of these states and is described by transcription activation rates α, β and γ respectively. Note that these activation rates include binding equilibria for transcription factor binding, and there is no cooperativity.
