Nuclear Protein Sorting

Nuclear Protein Sorting

Nuclear protein sorting is the selective trafficking of histones, polymerases, gene regulatory proteins into the nucleus and exporting RNAs and ribosomes to the cytosol. It is a tightly controlled process that regulates gene expression within a cell.
Proteins targeted to the nucleus carry nuclear localization signals or NLS recognized by import receptors in the cytosol. Similarly, proteins with nuclear export signals are recognized by export receptors. Import and export receptors are...

Microbes and Other Elemental Cycles

Microbes 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...

Cell Inclusions

Cell Inclusions

Prokaryotic cells possess a variety of inclusions that play crucial roles in nutrient storage, metabolic processes, and environmental adaptation. These structures enable bacteria to thrive under fluctuating environmental conditions by storing essential resources and optimizing their metabolic efficiency.Carbon Storage: Poly-β-Hydroxybutyric Acid and Glycogen GranulesBacteria frequently store excess carbon in specialized granules. Poly-β-hydroxybutyric acid (PHB) granules are lipid polymers that...

Chemistry of the Cell

Chemistry of the Cell

The cell is chemically composed of water, organic molecules and inorganic ions.
Water
The polarity of the water molecule and its resulting hydrogen bonding makes water a unique substance with special properties that are intimately tied to the processes of life. Life originally evolved in an aqueous environment, and most of an organism’s cellular chemistry and metabolism occur inside the aqueous contents of the cell’s cytoplasm. Special properties of water are its high heat capacity and heat of...

Properties of Organometallic Compounds

Properties of Organometallic Compounds

Organometallic compounds are compounds that contain a carbon–metal bond. Carbon belongs to an organyl group like alkyl, aryl, allyl, or benzyl groups. The metal can be from Group I or Group II of the periodic table, a transition metal, or a semimetal.

Proteomics

Proteomics

A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term proteomics...

Area of Science:

Biochemistry
Systems Biology
Bioinorganic Chemistry

Background:

Living systems exhibit complex interactions with inorganic elements.
Current research needs to integrate these interactions into a broader 'omics' framework.
The metallome, encompassing all metal-binding biomolecules, offers a potential framework.

Purpose of the Study:

To define and explore the concept of the metallome.
To highlight the necessity of an 'omics' approach using bioinformatics and IT.
To frame metallomics within a cellular context for systems biology.

Main Methods:

Conceptual framework development.
Bioinformatics and information technology integration.
Definition of metallome and its subsets (e.g., metalloproteome).

Main Results:

The metallome is defined as all biomolecules interacting with metal ions or inorganic elements.
Subsets of the metallome, such as the metalloproteome, are identified.
The need for a systems biology perspective integrating cellular metal ion pathways is established.

Conclusions:

Understanding metal-biomolecule interactions requires an integrated, systems biology approach.
Bioinformatics and IT are crucial for advancing metallomics research.
Framing the metallome within the cell is essential for a holistic view.
