Figure 4From: Integration of transcriptional inputs at promoters of the arabinose catabolic pathwayCalculated transcription factor activity during diauxic shift. The period of glucose starvation is indicated by the peak in CRP-cAMP activity. Activity is calculated using equation 2 from measurements of synRNAP-σ70, synCRP and synARA expression. These profiles represent mean expression from n = 7 experiments with time 0 normalized to the start of glucose exhaustion.Back to article page
