1. Differential Biosynthesis and Roles of Two Ferrichrome-Type Siderophores, ASP2397/AS2488053 and Ferricrocin, in Acremonium persicinum

Ferrichromes are a family of fungal siderophores with cyclic hexapeptide structures. Most fungi produce one or two ferrichrome-type siderophores. Acremonium persicinum MF-347833 produces ferrichrome-like potent Trojan horse antifungal antibiotics ASP2397 and AS2488053, the aluminum- and iron-chelating forms of AS2488059, respectively. Here, we show by gene sequencing followed by gene deletion experiments that A. persicinum MF-347833 possesses two nonribosomal peptide synthetase genes responsible for AS2488059 and ferricrocin assembly. AS2488059 was produced under iron starvation conditions and excreted into the media to serve as a defense metabolite and probably an iron courier. In contrast, ferricrocin was produced under iron-replete conditions and retained inside the cells, likely serving as an iron-sequestering molecule. Notably, the phylogenetic analyses suggest the different evolutionary origin of AS2488059 from that of conventional ferrichrome-type siderophores. Harnessing two ferrichrome-type siderophores with distinct biological properties may give A. persicinum a competitive advantage for surviving the natural environment.
2. De novo synthesis of ferrichrome by Fusarium oxysporum f. sp. cubense TR4 in response to iron starvation
Evans Were, Jochen Schöne, Altus Viljoen, Frank Rasche Fungal Biol. 2022 Aug;126(8):521-527. doi: 10.1016/j.funbio.2022.05.005. Epub 2022 May 27.
Manipulation of iron bioavailability in the banana rhizosphere may suppress Fusarium wilt, caused by Fusarium oxysporum f. sp. cubense (Foc). However, iron starvation induced by application of synthetic iron chelators does not effectively suppress Fusarium wilt. It is unclear whether Foc can subvert iron chelators and thereby evade iron starvation through the synthesis of iron-scavenging secondary metabolites, called siderophores. In vitro studies were conducted using iron-deficient growth medium and medium supplemented with a synthetic iron chelator, 2,2'-dipyridyl, to mimic iron starvation in Foc Tropical Race 4 (Foc TR4). Concentration of extracellular siderophores increased three-fold (p < 0.05) in the absence of iron. Liquid chromatography-mass spectrometry analysis detected the hydroxamate siderophore, ferrichrome, only in the mycelia of iron-starved cultures. Moreover, iron-starved cultures exhibited a reduction in total cellular protein concentration. In contrast, out of the 20 proteinogenic amino acids, only arginine increased (p < 0.05) under iron starvation. Our findings suggest that iron starvation does not cause a remodelling of amino acid metabolism in Foc TR4, except for arginine, which is required for biosynthesis of ornithine, the precursor for siderophore biosynthesis. Collectively, our findings suggest that biosynthesis of siderophores, particularly ferrichrome, could be a counteractive mechanism for Foc TR4 to evade iron starvation.
3. Ferrichrome, a fungal-type siderophore, confers high ammonium tolerance to fission yeast
Po-Chang Chiu, Yuri Nakamura, Shinichi Nishimura, Toshitsugu Tabuchi, Yoko Yashiroda, Go Hirai, Akihisa Matsuyama, Minoru Yoshida Sci Rep. 2022 Oct 27;12(1):17411. doi: 10.1038/s41598-022-22108-0.
Microorganisms and plants produce siderophores, which function to transport environmental iron into cells as well as participate in cellular iron use and deposition. Their biological functions are diverse although their role in primary metabolism is poorly understood. Ferrichrome is a fungal-type siderophore synthesized by nonribosomal peptide synthetase (NRPS). Herein we show that ferrichrome induces adaptive growth of fission yeast on high ammonium media. Ammonium is a preferred nitrogen source as it suppresses uptake and catabolism of less preferred nitrogen sources such as leucine through a mechanism called nitrogen catabolite repression (NCR). Therefore, the growth of fission yeast mutant cells with leucine auxotrophy is suppressed in the presence of high concentrations of ammonium. This growth suppression was canceled by ferrichrome in a manner dependent on the amino acid transporter Cat1. Additionally, growth retardation of wild-type cells by excess ammonium was exacerbated by deleting the NRPS gene sib1, which is responsible for the biosynthesis of ferrichrome, suggesting that intrinsically produced ferrichrome functions in suppressing the metabolic action of ammonium. Furthermore, ferrichrome facilitated the growth of both wild-type and sib1-deficient cells under low glucose conditions. These results suggest that intracellular iron regulates primary metabolism, including NCR, which is mediated by siderophores.
