Fungi utilize high-affinity chelators termed siderophores with chemically diverse structures to scavenge the essential nutrient iron from their surroundings. As they are among the strongest known Fe3+ binding agents, intracellular release of the heavy metal atom is facilitated by the activity of specific hydrolases. In this work, we report the characterization and x-ray structures of four siderophore esterases, AfEstB and AfSidJ from Aspergillus fumigatus, as well as AnEstB and AnEstA from Aspergillus nidulans. Even though they all display the conserved alpha/beta-hydrolase fold, we found remarkable structural and enzymatic discrepancies in their adaption to both related and chemically diverse substrates. A complex structure of AfEstB and its substrate triacetylfusarinine C gives insights into an active enzyme, with a tetrahedral coordination between the catalytic serine and the scissile ester bond. | |||
