Connectivity of essential nodes.
(a) Essential nodes tend to be more highly connected in the LC-PI and LC-GI networks.
k is the measure of connectivity. (b) Essential-essential interactions are significantly enriched in the LC-PI and HTP-PI
datasets but to a lesser extent in the LC-GI dataset. NN, nonessential-nonessential
pairs; NE, nonessential-essential pairs, EE, essential-essential pairs. (c) The fraction of neighbors that are essential for LC-PI and HTP-PI networks. Only those
nodes with connectivity greater than 3 were considered (n = 1,473 for LC-PI and n = 1,627 for HTP-PI). Compared with HTP-PI, a larger fraction of the immediate neighborhood
of essential proteins in the LC-PI is composed of essential genes. (d) Clustering coefficient distribution for physical networks (top panel) and genetic
networks (bottom panel). Average clustering coefficients and correlation coefficients
were respectively: 0.53 and -0.56 for LC-PI, 0.38 and -0.54 for HTP-PI, 0.50 and -0.61
for LC-GI, 0.53 and -0.67 for HTP-GI. All correlations were computed using Spearman
rank correlation and were statistically significant at P < 1e-100.
