Nitrogenase dedicated ferric iron and molybdate transport in A. ferrooxidans . A. Genomic context and gene organization of the predicted bifunctional Fe and Mo transport operon. B. Model for A. ferrooxidans dedicated metal import for nitrogenase function. Colors in the membrane model correspond to genes in the gene context scheme. â– : Fur box. Violet: Genes encoding nitrogenases. Orange : genes encoding bifunctional metal transporters. AT: A. thiooxidans. AF: A. ferrooxidans. AC: A. caldus.
