FIGURE 1. Network representation for 869 protein sequences of
the “PETase core domain” linked by 318,773 edges. The protein
sequences depicted here were selected by clustering at a threshold of
90% sequence identity. Edges (links) were selected at a threshold of
55% sequence similarity. Nodes are coloured according to their
annotated source organisms, with Actinobacteria in red ⬤, Proteobacteria
in blue ⬤, Fungi in cyan ⬤, Bacteroidetes in orange ⬤, other bacteria
from the FCB group in yellow ⬤, Planctomycetes in green ⬤, and unknown
bacteria coloured in white ○. See Methods section for more details on
the network layout. Supplementary figures are available inFigures S2 and S3 .
