▪ Abstract The ability of pathogens to obtain iron from transferrins, ferritin, hemoglobin, and
other iron-containing proteins of their host is central to whether they live or die. To combat …

Cyanobacteria, broadly classi¢ ed as oxygenic phototrophs containing chlorophyll-a and
accessory pigments, are among the oldest life forms on earth. They may be unicellular …

The mycobacterial IdeR protein is a metal-dependent regulator of the DtxR (diphtheria toxin
repressor) family. In the presence of iron, it binds to a specific DNA sequence in the …

Like other bacterial species, Mycobacterium tuberculosis has multiple sigma (σ) factors
encoded in its genome. In previously published work, we and others have shown that …

The proteins belonging to the Fur family are global regulators of gene expression involved in
the response to several environmental stresses and to the maintenance of divalent cation …

In this work, we characterize genes in Mycobacterium tuberculosis that are regulated by
IdeR (i ron‐de pendent r egulator), an iron‐responsive DNA‐binding protein of the DtxR …

The Bacillus subtilis yqhN gene encodes a metalloregulatory protein distantly related to the
Corynebacterium diphtheriae diphtheria toxin repressor (DtxR). While DtxR mediates the …

The discovery of molecules capable of presenting lipid antigens, the CD1 family, and of the
T cells that recognize them, has opened a new dimensionin our understanding of cell …

Unlike major histocompatibility proteins, which bind peptides, CD1 proteins display lipid
antigens to T cells. Here, we report that CD1a presents a family of previously unknown …

Fluorescent reporter proteins have proven useful for imaging techniques in many organisms.
We constructed optimized expression systems for several fluorescent proteins from the far …
