Summary
Iron-sulfur (Fe-S) clusters are vital for cellular functions. Defects in their assembly pathway can cause various human diseases, highlighting a broad spectrum of potential genetic disorders.
Area of Science:
- Biochemistry
- Molecular Biology
- Genetics
Background:
- Iron-sulfur (Fe-S) clusters are critical cofactors for numerous biological processes.
- Fe-S cluster assembly proteins are encoded by single genes in humans, and mutations can lead to inherited diseases.
Purpose of the Study:
- To explore the spectrum of human diseases linked to Fe-S cluster biogenesis defects.
- To investigate the potential of mutations in Fe-S cluster assembly genes causing novel human disorders.
Main Methods:
- Review of existing literature on Fe-S cluster assembly proteins and associated diseases.
- Analysis of known genetic defects and their clinical manifestations.
Main Results:
- Fe-S cluster biogenesis defects are linked to Friedreich ataxia, sideroblastic anemia, and myopathy.
- Mutations in other Fe-S cluster assembly genes may cause diseases with unique tissue-specific impairments.
Conclusions:
- The iron-sulfur cluster biogenesis pathway is implicated in a wider range of human diseases than previously recognized.
- Further investigation into Fe-S cluster assembly genes may uncover novel genetic causes for various human pathologies.

01:20Sulfur Assimilation
Sulfur is an essential element in biological systems, contributing to synthesizing key biomolecules, including amino acids such as cysteine and methionine, and cofactors such as coenzyme A and biotin. Microorganisms primarily assimilate sulfur as sulfate (SO₄²⁻) from the environment, which must undergo a series of biochemical transformations before it can be incorporated into cellular components. As sulfate is highly oxidized, it must undergo assimilatory sulfate reduction to become...
01:24Microbes and Other Elemental Cycles
Microbial activity plays a pivotal role in the biogeochemical cycling of iron and manganese, especially at the redox gradients characteristic of stratified aquatic environments. These cycles are driven by microbial transformations between oxidized and reduced forms of the metals, allowing organisms to exploit them for metabolic energy and structural purposes.Iron Cycling Across Redox GradientsIn neutral, oxygen-rich surface waters, iron is predominantly found in its oxidized, insoluble ferric...
03:03Amyloid Fibrils
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining, normally used to...

01:28Microbial Nutrition
Organisms exhibit remarkable metabolic diversity, categorized based on how they acquire energy and carbon. These strategies enable survival in various ecological niches and are essential for maintaining energy flow and nutrient cycling within ecosystems.Energy and Carbon SourcesOrganisms are classified as phototrophs or chemotrophs based on energy acquisition. Phototrophs use light as their energy source, while chemotrophs rely on oxidizing chemical compounds. Further differentiation arises...
01:29Microbes and the Sulfur Cycle
Sulfur is a vital element in Earth's biogeochemical systems. It transitions through various inorganic states, including sulfate (SO₄²⁻), elemental sulfur (S⁰), and sulfide (S²⁻). Abiotic and biological mechanisms across oxic and anoxic environments intricately mediate these transformations. Sulfate, the most oxidized form of sulfur, is predominantly stored in rocks, marine sediments, and oceanic waters, acting as a long-term reservoir in the global sulfur cycle.In oxic environments,...
01:45Vesicular Tubular Clusters
After budding out from the ER membrane, some COPII vesicles lose their coat and fuse with one another to form larger vesicles and interconnected tubules called vesicular tubular clusters or VTCs. These clusters constitute a compartment at the ER-Golgi interface known as ERGIC (Endoplasmic Reticulum Golgi Intermediate Compartment). The ERGIC is a mobile membrane-bound cargo transport system that sorts proteins secreted from ER and delivers them to the Golgi.
