Cells growing in aerobic environments have developed intricate strategies to overcome the
scarcity of iron, an essential nutrient. In Gram‐negative bacteria, high‐affinity iron acquisition …

Dr. Heinonen reviews and critically evaluates the scientific literature on the biological role of
inorganic pyrophosphate (PPi) published from 1940 to the end of 1999. He describes and …

Anthracnose, caused by the fungus Colletotrichum acutatum is one of the most important
diseases in strawberry crop. Due to environmental pollution and resistance produced by …

The function of the ABC transporter Atm1p located in the mitochondrial inner membrane is
not yet known. To study its cellular role, we analyzed a mutant in which ATM1 was disrupted …

The Bacillus subtilis ferric uptake repressor (Fur) protein coordinates a global transcriptional
response to iron starvation. We have used DNA microarrays to define the Fur regulon and …

The Escherichia coli mntH (formerly yfeP) gene encodes a putative membrane protein
(MntH) highly similar to members of the eukaryotic Nramp family of divalent metal ion …

Iron acquisition in Yersinia pestis is fundamental to the success of plague pathogenesis. We
have previously identified an≈ 5.6 kb region (yfe) of Y. pestis genomic DNA, capable of …

In this study, we identified the iron‐transport systems of Escherichia coli O157: H7 strain
EDL933. This strain synthesized and transported enterobactin and had a ferric citrate …

Iron is important for bacterial growth and survival, as it is a common co-factor in essential
enzymes. Although iron is very abundant in the earth crust, its bioavailability is low in most …

Several novel but similar heavy metal ion transporters, Zrt1, Zrt2, Zip1-4 and Irt1, have
recently been characterized. Zrt1, Zrt2 and Zip1-4 are probably zinc transporters in …
