Figure 5From: Transcriptional regulatory network refinement and quantification through kinetic modeling, gene expression microarray data and information theoryTF activity time courses for 16 of 38 TFs. These results are in qualitative agreement with those obtained by Kao et al. (2003) except for PhoB. pstC and pstS are upregulated by PhoB and their level of expression increases in time (shown in Figure 6), therefore one would expect the activity of PhoB to increase as well.Back to article page
