Structural Analysis and Inhibitor Modeling of Bacterioferritin From Brucella abortus

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Iron homeostasis in various pathogenic bacteria is regulated by bacterioferritins (Bfr) which function to store Fe3+ and release Fe2+ as needed for metabolic processes. The Bfr structure consists of 18 kDa subunits in which dimer pairs bind a heme molecule and are assembled into a highly symmetrical 24‐meric spherical structure with an ...

Mitochondria as a Possible Place for Initial Stages of Steroid Biosynthesis in Plants [PDF]

open access: yesJournal of Stress Physiology & Biochemistry, 2014
With the aim of thorough comparison of steroidogenic systems of plants and animals, transgenic plants of Solanaceae family expressing CYP11A1 cDNA encoding cytochrome P450SCC of mammalian mitochondria were further analysed.

Immunological comparison of ferredoxins [PDF]

open access: yesFEBS Letters, 1975
1. Introduction The biological significance of ferredoxins in various processes, and the increasing number of them that have been isolated and characterized from bacterial, plant and animal systems, have stimulated investigations on the physico-chemical properties of these proteins [ 1,2].

Versatile High‐Sensitivity EPR Using Superconducting Spiral Microresonators

open access: yesSmall Methods, EarlyView.
A significant sensitivity enhancement in conventional X‐band pulsed EPR is achieved using planar spiral microresonators fabricated from high‐temperature superconducting YBCO. Fully compatible with standard instrumentation, the approach enables high‐fidelity spin control under typical sample conditions.

The return of metabolism: biochemistry and physiology of glycolysis

open access: yesBiological Reviews, EarlyView.
ABSTRACT Glycolysis is a fundamental metabolic pathway central to the bioenergetics and physiology of virtually all living organisms. In this comprehensive review, we explore the intricate biochemical principles and evolutionary origins of glycolytic pathways, from the classical Embden–Meyerhof–Parnas (EMP) pathway in humans to various prokaryotic and ...

Taxonomic and functional shifts in the microbiome of severely obese, prediabetic patients: Ketogenic diet versus energy‐matched standard diet

open access: yesDiabetes, Obesity and Metabolism, EarlyView.
Abstract Aims Obesity and type 2 diabetes mellitus (T2DM) are among the leading global health challenges of the 21st century. While caloric restriction remains the cornerstone of weight loss interventions, ketogenic diets (KD), characterised by low carbohydrate and high fat intake, have been shown to improve metabolic health partly by modulating the ...

Ferredoxin containing bacteriocins suggest a novel mechanism of iron uptake in Pectobacterium spp.

open access: yesPLoS ONE, 2012
In order to kill competing strains of the same or closely related bacterial species, many bacteria produce potent narrow-spectrum protein antibiotics known as bacteriocins. Two sequenced strains of the phytopathogenic bacterium Pectobacterium carotovorum

Phycocyanobilin biosynthesis in Galdieria sulphuraria requires isomerization of phycoerythrobilin synthesized by bilin reductases

open access: yesThe FEBS Journal, EarlyView.
The biosynthesis of bilins, tetrapyrroles essential for light harvesting and sensing, is performed by specific enzymes (FDBRs). In Galdieria sulphuraria, both phycobiliprotein types bind phycocyanobilin, despite lacking the canonical synthesizing gene PCYA. Instead, PEBA and PEBB are encoded, producing phycoerythrobilin, proposed to be later isomerized

ZmTH1 Is Vital for Healthy Plant Growth and Promotes Cold/Drought Tolerance by Regulating Thiamin Diphosphate‐Dependent Metabolisms in Maize

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Vitamin B1 (VB1) plays a crucial role in sustaining plant health and enabling adaptive responses to environmental stress. The complex maize genome implies a sophisticated VB1 synthesis pathway, with the mechanisms by which VB1 benefits plants remaining elusive.
