The plant pathogenic fungus <i>Fusarium graminearum</i> is known to produce a wide array of secondary metabolites during plant infection. This includes several nonribosomal peptides. Recently, the fusaoctaxin (<i>NRPS5</i>/9) and gramilin (<i>NRPS8</i>) gene clusters were shown to be induced by host interactions. To widen our understanding of this important pathogen, we investigated the involvement of the <i>NRPS4</i> gene cluster during infection and oxidative and osmotic stress. Overexpression of <i>NRPS4</i> led to the discovery of a new cyclic hexapeptide, fusahexin (<b>1</b>), with the amino acid sequence cyclo-(d-Ala-l-Leu-d-<i>allo</i>-Thr-l-Pro-d-Leu-l-Leu). The structural analyses revealed an unusual ether bond between a proline C<sup>δ</sup> to C<sup>β</sup> of the preceding threonine resulting in an oxazine ring system. The comparative genomic analyses showed that the small gene cluster only encodes an ABC transporter in addition to the five-module nonribosomal peptide synthetase (NRPS). Based on the structure of fusahexin and the domain architecture of <i>NRPS4</i>, we propose a biosynthetic model in which the terminal module is used to incorporate two leucine units. So far, iterative use of NRPS modules has primarily been described for siderophore synthetases, which makes <i>NRPS4</i> a rare example of a fungal nonsiderophore NRPS with distinct iterative module usage. << Less
