Kumar A, Yang T, Chakravorty S, Majumdar A, Nairn B, Six D, et al.
J Biol Chem
. 2022 Feb;
298(3):101651.
PMID: 35101443
Siderophores are iron-chelating molecules that solubilize Fe for microbial utilization and facilitate colonization or infection of eukaryotes by liberating host iron for bacterial uptake. By fluorescently labeling membrane receptors and...

Curr Opin Microbiol
. 2021 Nov;
65:95-100.
PMID: 34781095
Clostridioides difficile produces toxins TcdA and TcdB during infection. Since the severity of the illness is directly correlated with the level of toxins produced, researchers have long been interested in...

Majumdar A, Trinh V, Moore K, Smallwood C, Kumar A, Yang T, et al.
J Biol Chem
. 2020 Feb;
295(15):4974-4984.
PMID: 32098871
The outer membrane receptor FepA transports ferric enterobactin (FeEnt) by an energy- and TonB-dependent, but otherwise a mechanistically undetermined process involving its internal 150-residue N-terminal globular domain (N-domain). We genetically...

J Biol Chem
. 2019 Jan;
294(12):4682-4692.
PMID: 30679312
Sensitive assays of biochemical specificity, affinity, and capacity are valuable both for basic research and drug discovery. We created fluorescent sensors that monitor high-affinity binding reactions and used them to...

J Bacteriol
. 2017 Mar;
199(10).
PMID: 28242720
Gram-negative bacteria acquire ferric siderophores through TonB-dependent outer membrane transporters (TBDT). By fluorescence spectroscopic hgh-throughput screening (FLHTS), we identified inhibitors of TonB-dependent ferric enterobactin (FeEnt) uptake through FepA (EcoFepA). Among...

PMID: 28031282
Siderophore nutrition tests with strain NA1000 revealed that it utilized a variety of ferric hydroxamate siderophores, including asperchromes, ferrichromes, ferrichrome A, malonichrome, and ferric aerobactin, as well as hemin and...

PMID: 24981231
Spectroscopic analyses of fluorophore-labeled Escherichia coli FepA described dynamic actions of its surface loops during binding and transport of ferric enterobactin (FeEnt). When FeEnt bound to fluoresceinated FepA, in living...
