Frequencies of the selected Pfam families in the individual genomes and metagenomes. The data for each entry are rescaled by the total number of Pfam domains annotated to the microbial genome or metagenome. The color scale from grey to black indicates domain families that are present in low to high amounts, respectively. White indicates absent protein domains. The signs “+” and “-” indicate whether a protein domain was chosen in the respective experiment.
