Iron Physiology and Its Impact on Atopic Diseases: An EAACI Taskforce Report

Allergy, EarlyView.
ABSTRACT Iron is essential for oxygen transport, energy metabolism, and immune regulation. Yet iron deficiency is the most common micronutrient disorder across all age groups, affecting nearly one quarter of the global population. Iron deficiency triggers nutritional immunity, a host defense mechanism that withholds and redistributes iron, contributing

Interaction between flavin mononucleotide-containing azoreductase and azo dyes

, 2017
Azoreductase, a flavin mononucleotide-containing oxidoreductase from Escherichia coli, can catalyze the reduction of azo dyes to form aromatic amine compounds.

Unraveling the active site cover of coproheme decarboxylase from Listeria monocytogenes

The FEBS Journal, EarlyView.
During heme biosynthesis in Gram‐positive bacteria, coproheme decarboxylase (ChdC) catalyzes the conversion of four‐propionate substrate coproheme to the two propionate product heme b. Its active site is universally covered by a flexible linking loop. This study identifies an important histidine residue, which stabilizes the loop in a ChdC homolog.

Cytosolic delivery of bacterial metabolites by riboflavin transporters promotes MR1 antigen presentation and MAIT cell recognition

Immunology &Cell Biology, EarlyView.
VitBAg antigen presentation is promoted through a cytosolic pathway that reaches ligand‐receptive MR1 to present to MAIT cells, like the riboflavin transport pathway. Riboflavin solute carrier transporters can promote this MR1 presentation, but they are not essential for this role, suggesting redundant pathways to uptake VitBAg.

Alteration of Flavin Cofactor Homeostasis in Human Neuromuscular Pathologies

, 2021
The aim of this short review chapter is to provide a brief summary of the relevance of riboflavin (Rf or vitamin B2) and its derived cofactors flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD) for human neuromuscular bioenergetics ...

The structure of Chlamydomonas LOV1 as revealed by time-resolved serial synchrotron crystallography

IUCrJ
The photo-reaction of the LOV1 domain of the Chlamydomonas reinhardtii phototropin is investigated by room-temperature time-resolved serial crystallography. A covalent adduct forms between the C4a atom of the central flavin-mononucleotide chromophore and

Immune dysregulation in mania: A proof‐of‐concept platelet proteomics study

Psychiatry and Clinical Neurosciences, EarlyView.
Aims Bipolar disorder (BD) is a major psychiatric condition with a multifaceted and largely unknown pathophysiology. Mania, the defining feature of BD, remains underinvestigated. Proteomics offers a powerful, data‐driven, unbiased approach to uncover biological alterations.

Vitamin‐Responsive Disorders: From Molecular Basis to Clinical Presentation and Therapy

Journal of Inherited Metabolic Disease, Volume 49, Issue 4, July 2026.
ABSTRACT Vitamin‐dependent cofactors are essential for numerous metabolic reactions, and defects affecting their uptake, conversion, utilisation, or regeneration constitute a heterogeneous group of inherited metabolic disorders (IMDs). Although dietary vitamin intake is sufficient to sustain coenzyme synthesis in healthy individuals, it is insufficient

Enantioselective Synthesis of Lactic Acid From CO2 Using a Novel Pyruvate Decarboxylase in a Scalable Biocatalytic Cascade

Advanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
We report a scalable biocatalytic cascade that converts CO2 and acetaldehyde to pyruvate via a newly characterized pyruvate decarboxylase, followed by stereoselective reduction to lactic acid. The system enables fully switchable enantioselectivity using either L‐ or D‐lactate dehydrogenases.
