The extreme insolubility of iron limits the supply of most organisms by this metal which forms
an essential part of enzymes active in the energy-generating electron transport chains and …

Iron acquisition by bacteria is a concept that is embedded in both classical microbiology and
contemporary biochemistry. Early work by Warburg (1949) defined the bacterial requirement …

COMPOUNDS (SIDEROPHORES)* JB Neilands, Ph. D. Biochemistry Department, University …

The low concentration of free iron in body fluids creates bacteriostatic conditions for many
microorganisms and is therefore an important defense factor of the body against invading …

The significance of iron as a nutrient and its role in biological processes have major
consequences in areas of science ranging from geochemistry to human disease. Invading …

Siderophores are naturally occurring chelate compounds synthesized by microorganisms
and used to sequester the biologically essential but sparingly soluble ferric ion from their …

Siderophores (from the Greek:“iron carriers”) are defined as relatively low molecular weight,
ferric ion specific chelating agents elaborated by bacteria and fungi growing under low iron …

Iron is an essential element for all living things (with the exception perhaps of a few bacteria
in specialized environments). Incorporation of iron into biochemistry certainly occurred in the …

In the human body iron is present in growth-limiting amounts for bacteria. For this reason
intricate iron transport and iron regulatory systems evolved in bacteria to guarantee a …

Siderophores are biosynthetically produced and secreted by many bacteria, yeasts, fungi
and plants, to scavenge for ferric iron (Fe 3+). They are selective iron-chelators that have an …
