The NRPS Encoded by C. heterostrophus NPS6 Is Responsible for the Biosynthesis of Extracellular Siderophores.

HPLC analyses of broth (left; extracellular) and mycelial (right; intracellular) extracts from cultures of wild-type and C. heterostrophus Δnps6 strains. Analyses within each column represent the same proportion of the total extract injected in a 10-μL aliquot, 1-mL equivalent for the broth extracts and 10-mL equivalents for the mycelial extracts. Siderophore peaks are labeled as follows: coprogen (1), neocoprogen I (2), neocoprogen II (3), and ferricrocin (4).
