  abstract = {{M}agnetotactic bacteria ({MTB}) are a group of phylogenetically and physiologically diverse {G}ram-negative bacteria that synthesize intracellular magnetic crystals named magnetosomes. {MTB} are affiliated with three classes of {P}roteobacteria phylum, {N}itrospirae phylum, {O}mnitrophica phylum and probably with the candidate phylum {L}atescibacteria. {T}he evolutionary origin and physiological diversity of {MTB} compared with other bacterial taxonomic groups remain to be illustrated. {H}ere, we analysed the genome of the marine magneto-ovoid strain {MO}-1 and found that it is closely related to {M}agnetococcus marinus {MC}-1. {D}etailed analyses of the ribosomal proteins and whole proteomes of 390 genomes reveal that, among the {P}roteobacteria analysed, only {MO}-1 and {MC}-1 have coding sequences ({CDS}s) with a similarly high proportion of origins from {A}lphaproteobacteria, {B}etaproteobacteria, {D}eltaproteobacteria and {G}ammaproteobacteria. {I}nterestingly, a comparative metabolic network analysis with anoxic network enzymes from sequenced {MTB} and non-{MTB} successfully allows the eventual prediction of an organism with a metabolic profile compatible for magnetosome production. {A}ltogether, our genomic analysis reveals multiple origins of {MO}-1 and {M}. marinus {MC}-1 genomes and suggests a metabolism-restriction model for explaining whether a bacterium could become an {MTB} upon acquisition of magnetosome encoding genes.},
