The benzoquinone ubiquinone (coenzyme Q) and the naphthoquinones menaquinone
(vitamin K 2) and demethylmenaquinone are derived from the shikimate pathway, which has …

Bacillus subtilis was reported to produce the catecholic siderophore itoic acid (2, 3-
dihydroxybenzoate (DHB)-glycine) in response to iron deprivation. However, by inspecting …

The Staphylococcus aureus genome encodes three ferric uptake regulator (Fur)
homologues: Fur, PerR, and Zur. To determine the exact role of PerR, we inactivated the …

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 …

Eight genes have been identified that function in the regulation, biosynthesis, and transport
of rhizobactin 1021, a hydroxamate siderophore produced under iron stress by …

Human milk provides infants with nutrients, hormones, enzymes and growth factors. These
substances contribute to the child's health and offer protection against infectious diseases …

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 …

McKay et al.[(1996) Science 273, 924–930] suggested that carbonate globules in the
meteorite ALH84001 contained the fossil remains of Martian microbes. We have …

Uptake of plutonium and uranium mediated by the siderophore desferrioxamine-B (DFOB)
has been studied for the common soil aerobe Microbacterium flavescens (JG-9). M …

Cyanobacteria are prominent constituents of the marine biosphere that account for a
significant percentage of oceanic primary productivity. In an effort to resolve how open …
