Figure 7From: Comparative genomic analyses of nickel, cobalt and vitamin B12 utilizationNi- and Co-dependent metalloproteomes in archaea. All organisms containing Ni or Co users are shown. Methanogenic phyla are shown in red. All methanogens possess larger Ni-dependent metalloproteomes than other archaeal phyla. Only Methanosarcina species (Methanosarcinales) have large Co-dependent metalloproteomes.Back to article page
