Statistics for the genome-wide survey of 19 E. coli strains. The different statistics obtained from the GWS have been represented in this figure. In panels a and b, the pathogenic strains have been represented in red and the non-pathogenic ones in green. The non-pathogenic strains have also been highlighted with green boxes. a. The number of RBPs in each strain. The pathogenic O26:H11 strain encodes the highest number of RBPs in its proteome. b. The percentage of RBPs in the proteome of each strain. These percentages have been calculated with respect to the proteome size of the strain under consideration. The difference in this number among the pathogenic and the non-pathogenic strains are insignificant (Welch Two Sample t-test: t = 3.2384, df = 2.474, p-value = 0.06272). c. The type of Pfam domains encoded by each strain. The difference in the types of Pfam domains, as well as Pfam RBDs, encoded by the pathogenic and the non-pathogenic strains are insignificant (Welch Two Sample t-test for types of Pfam domains: t = −1.3876, df = 2.263, p-value = 0.2861; Welch Two Sample t-test for types of Pfam RBDs: t = −0.9625, df = 2.138, p-value = 0.4317). d. The abundance of Pfam RBDs. 185 types of Pfam RBDs were found to be encoded in the RBPs, of which DEAD domains have the highest representation (approximately 4% of all Pfam RBDs)
