  1. Proteins with metal ion binding properties were identified using Gene Ontology function search through the Joint Genome Institute – Integrated Microbial Genomes website (https://img.jgi.doe.gov). Identified protein domains for the metalloproteins were used to find orthologs in Frankia and other bacteria including: Bacillus subtilis subtilis 168 (B sub), Cupriavidus metallidurans CH34 (C met), Escherichia coli K12- W3110 (E col), Helicobacter pylori B8 (H pyl), Mycobacterium tuberculosis H37Rv (M tub), and Streptomyces viridochromogenes DSM 40736 (S vir). Genomes with significant (>1 S.D. from average) metalloprotein content, normalized to the genome size, are in bold. % MPs = percentage of total metalloproteins in the genome. %MR = percent metal resistance genes (binding, detoxification, and export) in the genome. [Dom #] = Number of unique protein families (pfam) or ortholog clusters (COG) that bind the indicated metal.
  2. a. Total number of protein coding genes in each genome.
