Figure 1From: Comparative analysis of the transcription-factor gene regulatory networks of E. coli and S. cerevisiaeRepresentation of the E. coli transcriptional regulatory network. a) Representation of the transcription-factor gene regulatory network of E. coli. Green circles represent transcription factors, brown circles denote regulated genes, and those with both functions are coloured in red. Projections of the network onto b) transcription factor and onto c) regulated gene nodes are also shown.Back to article page
