Functionality of sncRNAs. (a) Scatter plot between the connectivity degree of the sncRNAs (k) and degree of functionality (V). The outlier (black point) corresponds to gene sgrS, which is a particular sncRNA that also codifies for a small polypeptide (43 amino acids). (b) Scatter plot between degree of functionality (V) and γ, which is the slope of the linear regression between the mutational and environmental robustness for all sequences that have a common structure. For this plot, a representative subset of sncRNA structures was considered (genes C0293, C0664, dsrA, ffs, gcvB, glmY, micA, oxyS, psrN, rydC, ryhB, sokC, and ssrA).
