FIG 3.

Both Alteromonas macleodii strains CUKW and KCC02 harbor a plasmid on which are located numerous genes for conferring metal, specifically copper, tolerance. Genes from the following categories are illustrated on both pCUKW-178 and pKCC02-243: mobile genetic elements (pink), conjugation and plasmid maintenance (purple), mercury transport/resistance (red), CusA/Czc heavy metal efflux (green), RND transporters (orange), copper resistance (dark blue). Light blue indicates the size and orientation of the remaining genes on the plasmid.
