Figure 3From: A network perspective on the topological importance of enzymes and their phylogenetic conservationRanked distribution of enzymes according to phylogenetic profile. The solid line represents the observed data from the KEGG database. The dotted line represents the expected phylogenetic profile for individual ranks (see Methods). The observed rank abundance distribution is significantly different from that expected (Χ2 = 67299.55, p ≈ 0, d.f. = 1080).Back to article page
