A [4Fe-4S] cluster resides at the active center of phosphomevalonate dehydratase, a key enzyme in the archaeal modified mevalonate pathway

Frontiers in Microbiology, 2023
The recent discovery of the archaeal modified mevalonate pathway revealed that the fundamental units for isoprenoid biosynthesis (isopentenyl diphosphate and dimethylallyl diphosphate) are biosynthesized via a specific intermediate, trans ...

Low-energy spectrum of iron-sulfur clusters directly from many-particle quantum mechanics [PDF]

, 2014
FeS clusters are a universal biological motif. They carry out electron transfer, redox chemistry, and even oxygen sensing, in diverse processes including nitrogen fixation, respiration, and photosynthesis. The low-lying electronic states are key to their

TusA influences Fe-S cluster assembly and iron homeostasis in E. coli by reducing the translation efficiency of Fur

Microbiology Spectrum
All sulfur transfer pathways have generally a l-cysteine desulfurase as an initial sulfur-mobilizing enzyme in common, which serves as a sulfur donor for the biosynthesis of numerous sulfur-containing biomolecules in the cell.

Evolutionary conservation and in vitro reconstitution of microsporidian iron–sulfur cluster biosynthesis

Nature Communications, 2017
The functions of the highly reduced mitochondria (mitosomes) of microsporidians are not well-characterized. Here, the authors show that theTrachipleistophora hominismitosome is the site of iron–sulfur cluster assembly and that its retention is likely ...

NsrR from Streptomyces coelicolor is a nitric oxide-sensing [4Fe-4S] cluster protein with a specialized regulatory function [PDF]

, 2015
The Rrf2 family transcription factor NsrR controls expression of genes in a wide range of bacteria in response to nitric oxide (NO). The precise form of the NO-sensing module of NsrR is the subject of controversy because NsrR proteins containing either ...

Functional Characterization of the Eukaryotic Cysteine Desulfurase Nfs1p from Saccharomyces cerevisiae [PDF]

, 2004
Previous studies have indicated that the essential protein Nfs1 performs a crucial role in cellular iron-sulfur (Fe/S) protein maturation. The protein is located predominantly in mitochondria, yet low amounts are present in cytosol and nucleus.

Genetic/metabolic effect of iron metabolism and rare anemias

Thalassemia Reports, 2013
Advances in iron metabolism have allowed a novel classification of iron disorders and to identify previously unknown diseases. These disorders include genetic iron overload (hemochromatosis) and inherited iron-related anemias, in some cases accompanied ...

Structures and proton-pumping strategies of mitochondrial respiratory enzymes [PDF]

, 2001
Enzymes of the mitochondrial respiratory chain serve as proton pumps, using the energy made available from electron transfer reactions to transport protons across the inner mitochondrial membrane and create an electrochemical gradient used for the ...
