Figure 3From: Stringent response of Escherichia coli: revisiting the bibliome using literature miningProteins co-annotated with ppGpp, pppGpp and the collective (p)ppGpp entities. The nodes represent proteins with frequency of co-annotation higher than 10%. Highly co-annotated proteins are represented by nodes with a larger size (frequencies of co-annotation greater than 50%). Pink nodes represent the proteins that were co-annotated with the three entities, while green and yellow nodes indicate the proteins that were co-annotated with only two and one of the nucleotides, respectively.Back to article page
