Receptor uptake arrays for vitamin B12, siderophores and glycans shape bacterial communities

, 2017
Molecular variants of vitamin B12, siderophores and glycans occur. To take up variant forms, bacteria may express an array of receptors. The gut microbe Bacteroides thetaiotaomicron has three different receptors to take up variants of vitamin B12 and 88 ...

The Hemoprotein Hhy1 Promotes Heme‐Dependent Catalase Activity of Ctt1

Molecular Microbiology, Volume 125, Issue 5, Page 389-411, May 2026.
A Schizosaccharomyces pombe strain deficient in heme (hem1Δ) and siderophore (Fc) biosynthesis, as well as high‐affinity iron (Fe) uptake (blue), was used to uncover the hemoprotein Hhy1 that promotes the heme‐dependent activity of the catalase Ctt1. In contrast, hhy1Δ cells exhibit reduced Ctt1 activity and increased sensitivity to oxidative stress ...

Deciphering the biosynthetic pathways of lichen acids

New Phytologist, Volume 250, Issue 3, Page 1784-1799, May 2026.
Summary Depsides and depsidones are polyketide‐derived lichen acids widely distributed in lichen thalli, yet the biosynthetic gene clusters (BGCs) responsible for their production remain poorly understood. To address this gap, we investigated the diversity and evolutionary relationships of polyketide BGCs in lichens.

Petrobactin Protects against Oxidative Stress and Enhances Sporulation Efficiency in Bacillus anthracis Sterne

mBio, 2018
Bacillus anthracis is a Gram-positive bacillus that under conditions of environmental stress, such as low nutrients, can convert from a vegetative bacillus to a highly durable spore that enables long-term survival. The sporulation process is regulated by

SIDEROPHORES FOR SELECTIVE SOLID PHASE EXTRACTION OF STRATEGIC ELEMENTS [PDF]

, 2018
All over the world, industrial mining is leaving contaminated areas and dumps that, although being full of valuable metals, have high concentrations of toxic heavy metals that pollute the environment.

Clearing the Noise: Seasonal Dynamics of Endophytic Bacteria in Fagus sylvatica Leaves Revealed by Application of PNA Clamps

Physiologia Plantarum, Volume 178, Issue 3, May/June 2026.
ABSTRACT The characterization of the seasonal dynamics of endophytic bacteria in beech leaves can be hindered by co‐amplification of chloroplast and mitochondrial plant DNA. This study applies established peptide nucleic acid (PNA) clamps to suppress host‐derived amplification while resolving bacterial succession across the vegetative season ...

Siderophore production by uropathogenic Escherichia coli

Indian Journal of Pathology and Microbiology, 2009
Urinary tract infection (UTI) is one of the most frequently encountered problems in ambulatory medicine. The present study was designed to determine siderophore production as the urovirulence factor of Escherichia coli isolated from the patients of UTI ...

Nanoassemblies of an Artificial Ferric Enterobactin Analog for Biosensing Enterobacteriaceae

ChemElectroChem, Volume 13, Issue 8, 15 April 2026.
Nanoassemblies of an artificial trisamine‐based Ferric Enterobactin, analogs to natural enterobactin and ferric enterobactin, is reported as molecular recognition receptors for real‐time biosensing. The electrochemical sensors, made from the nanoassemblies of its iron(III)complex, exhibit rapid anodic peak current changes upon exposure to live cells of

Specificity and mechanism of TonB-dependent ferric catecholate uptake by Fiu

Frontiers in Microbiology
We studied the Escherichia coli outer membrane protein Fiu, a presumed transporter of monomeric ferric catecholates, by introducing Cys residues in its surface loops and modifying them with fluorescein maleimide (FM).

Fortifying plant fortresses: siderophores in defense against Cercospora leaf spot disease in Vigna radiata L.

Frontiers in Microbiology
Siderophores, specialized iron-chelating molecules produced by Bacillus amyloliquefaciens D5, were investigated for their role in enhancing plant defense mechanisms against Cercospora canescens in mung bean (Vigna radiata L.). Siderophores were extracted
