In a search for iron-regulated proteins of Aspergillus nidulans and Aspergillus fumigatus a
16-kDa protein was identified which is about 5-fold upregulated during iron starvation in …

It has been found that yeast mutants deficient in cytosolic superoxide dismutase CuZnSOD
are hypersensitive to ferrous iron. In contrast mutants that are deficient in catalases and …

A current hypothesis explaining the toxicity of superoxide anion in vivo is that it oxidizes
exposed [4Fe-4S] clusters in certain vulnerable enzymes causing release of iron and …

Cu, Zn-superoxide dismutase plays an important role in protecting cells from oxygen toxicity
by catalyzing the dismutation of superoxide anion into hydrogen peroxide and oxygen. In …

The iron superoxide dismutase (FeSOD) gene of Escherichia coli was cloned in
Saccharomyces cerevisiae cells deficient in copper, zinc superoxide dismutase (Cu …

Yeast, like most eukaryotes, contain manganese superoxide dismutase (MnSOD; product of
the SOD2 gene) in the mitochondria and copper, zinc superoxide dismutase (Cu, ZnSOD; …

A wild-type strain of the yeast Saccharomyces cerevisiae grown at a medium [Cu] of less
than or equal to 50 nM contained less Cu, Zn superoxide dismutase (SOD) mRNA (60%) …

One of the most important features that enables Aspergillus fumigatus to grow within a
susceptible individual and to cause disease is its ability to obtain Zn2+ ions from the …

Aspergillus fumigatus is a saprophyte fungus that typically grows on organic decaying matter
but can also parasitize immunosuppressed hosts. This is explained, in part, by its great …

Under conditions of low iron availability, most fungi excrete siderophores in order to mobilize
extracellular iron. We show that lack of the GATA‐type transcription factor SREA in …
