Agrobacterium tumefaciens
Production of siderophores also exhibited in some plant-infecting bacteria, such as "Agrobacterium tumefaciens". The enzyme is controlled by gene cluster agb and the production of 2,3-diDHB dehydrogenase is controlled by the gene agbA. The enzyme AgbA is homologous to the EntA enzyme in "E. coli", the same enzyme that produces 2,3-diDHB dehydrogenase.
