Iron is an essential trace element for most organisms. A common way for bacteria to acquire
this nutrient is through the secretion of siderophores, which are secondary metabolites that …

Plant growth performance under a stressful environment, notably in the agriculture field, is
directly correlated with the rapid growth of the human population, which triggers the …

Siderophores are small molecular weight iron scavengers that are mainly produced by
bacteria, fungi, and plants. Recently, they have attracted increasing attention because of …

Iron is a micronutrient for nearly all life on Earth. It can be used as an electron donor and
electron acceptor by iron-oxidizing and iron-reducing microorganisms and is used in a …

The microorganism-microorganism or microorganism-host interactions are the key strategy
to colonize and establish in a variety of different environments. These interactions involve all …

The ATP-binding cassette (ABC) transporter superfamily is found in all domains of life,
facilitating critical biological processes through the translocation of a wide variety of …

SUMMARY ATP-binding cassette (ABC) systems are universally distributed among living
organisms and function in many different aspects of bacterial physiology. ABC transporters …

Although iron is required to sustain life, its free concentration and metabolism have to be
tightly regulated. This is achieved through a variety of iron-binding proteins including …

Iron is an essential element for all microorganisms. Siderophores are low-weight, high-
affinity iron chelating molecules produced in response to iron deficiency by Gram-positive …

In this issue of Structure, Holmes et al.(2005) describe elements of an innate defense
mechanism that provides mammals a means to restrict bacterial growth. The host protein …
