Co-dependent metalloproteomes in bacteria. Numbers following the name of each phylum represent the number of organisms containing at least one B12-binding protein and that of total sequenced organisms, respectively. The largest Co-dependent metalloproteome was observed in Dehalococcoides sp. CBDB1 (35 B12-dependent proteins, 32 of which were CprAs) and Dehalococcoides ethenogenes (22 B12-dependent proteins, 19 of which were CprAs).
