Characterization of Two VAO-Type Flavoprotein Oxidases from Myceliophthora thermophila

Molecules, 2018
The VAO flavoprotein family consists mostly of oxidoreductases harboring a covalently linked flavin cofactor. The linkage can be either monocovalent at position 8 with a histidine or tyrosine or bicovalent at position 8 with a histidine and at position 6

The X‐Ray Crystal Structure of BorF, the Flavin Reductase Subunit of a Two‐Component Flavin‐Dependent Tryptophan Halogenase

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT BorF is a short‐chain flavin reductase from a desert soil bacterium that uses NADH to reduce FAD to FADH2, which is used by the tryptophan‐6‐halogenase BorH to chlorinate tryptophan in the biosynthetic pathway of borregomycin A. The X‐ray crystal structure of BorF bound to FAD was solved to 2.37 Å by molecular replacement.

Rotenone Induces Morphological Damage and Reduction in Catecholamine Levels in the Central Nervous System of the Ascidian Styela plicata

Environmental Toxicology, EarlyView.
ABSTRACT Ascidians are invertebrates that occupy a key phylogenetic position as a sister group of the vertebrates. The organization of their central nervous system (CNS), with cortex and medulla, indicates a plesiomorphic character of the gray and white matter of vertebrates, making this group of animals useful for studies of neurodegenerative events ...

The FAD Cofactor of RebC Shifts to an IN Conformation upon Flavin Reduction†,‡ [PDF]

, 2014
RebC is a putative flavin hydroxylase functioning together with RebP to carry out a key step in the biosynthesis of rebeccamycin. To probe the mechanism of flavin-based chemistry in RebC, we solved the structure of RebC with reduced flavin.

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

Two-Component FAD-Dependent Monooxygenases: Current Knowledge and Biotechnological Opportunities

Biology, 2018
Flavoprotein monooxygenases create valuable compounds that are of high interest for the chemical, pharmaceutical, and agrochemical industries, among others. Monooxygenases that use flavin as cofactor are either single- or two-component systems.

Dystrophia Smolandiensis is characterized by a novel NQO1 variant and a distinct phenotype from COL17A1‐associated epithelial recurrent erosion dystrophy

Acta Ophthalmologica, EarlyView.
Abstract Purpose To determine the molecular cause of the two epithelial recurrent erosion dystrophies, Dystrophia Smolandiensis and Dystrophia Helsinglandica, and to identify phenotypic differences between the two conditions. Methods DNA samples and clinical data from structured interview records were obtained from the Swedish families in which ...

D‐amino acid oxidase as a chemogenetic tool for spatiotemporally controlled hydrogen peroxide production: The oxygen connection

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose D‐amino acid oxidase (DAO) has been developed as a chemogenetic tool, to precisely manipulate redox levels in tissues and cells by generating H2O2 in the presence of D‐amino acids. The enzyme's significant oxygen consumption during H2O2 production may influence cellular oxygen levels.

Identification and characterization of a fluorescent flagellar protein from the brown alga Scytosiphon lomentaria (Scytosiphonales, Phaeophyceae): A flavoprotein homologous to Old Yellow Enzyme [PDF]

, 2005
The posterior flagellum of the zoospore of the brown alga Scytosiphon lomentaria exhibits bright green autofluorescence. To identify the fluorescent flagellar substance(s), we isolated flagella from zoospores and partially purified a flavoprotein by ...
