Siderophores are an important group of structurally diverse natural products that play key roles in ferric iron acquisition in most microorganisms. Two major pathways exist for siderophore biosynthesis. One is dependent on nonribosomal peptide synthetase (NRPS) multienzymes. The enzymology of several NRPS-dependent pathways to structurally diverse siderophores has been intensively studied for more than 10 years and is generally well understood. The other major pathway is NRPS-independent. It relies on a novel family of synthetase enzymes that until recently has received very little attention.
