Peroxisomes

Peroxisomes

Peroxisomes are specialized organelles present in fungi, plant, and animal cells. It can vary in number, size, morphology, and activity depending on the type of tissue and the nutritional state of the cell. For example, cells with active lipid metabolism, such as adipocytes, neurons, and hepatocytes, have more peroxisomes than other cells in the body. Besides their primary role in breaking down complex organic molecules, peroxisomes can also synthesize specific macromolecules and participate in...

Peroxisomes and Mitochondria

Peroxisomes and Mitochondria

Peroxisomes and mitochondria are two important oxygen-utilizing organelles in eukaryotic cells. Mitochondria carry out cellular respiration—the process that converts energy from food into ATP. Peroxisomes carry out a variety of functions, primarily breaking down different substances, such as fatty acids.
The peroxisome is a single membrane-bound cellular organelle that can perform several different functions, including lipid metabolism and chemical detoxification. The enzymes within peroxisomes...

Protein Import into the Peroxisomes

Protein Import into the Peroxisomes

Cells contain membrane-bound organelles called peroxisomes that oxidize organic molecules by transferring hydrogen atoms to oxygen, producing hydrogen peroxide. Peroxisomes enzymatically convert the released hydrogen peroxide into water and oxygen.
Peroxisomal Protein Import:
Peroxisomes lack the genetic machinery required to code for their own proteins. Hence, most peroxisomal membrane, lumenal and transmembrane proteins are synthesized in the cytoplasm or ER and transported to the peroxisome...

Oxidation of Phenols to Quinones

Oxidation of Phenols to Quinones

In the presence of oxidizing agents, phenols are oxidized to quinones. Quinones can be easily reduced back to phenols using mild reducing agents. The electron-donating hydroxyl group enhances the reactivity of the aromatic ring, enabling oxidation of the ring even in the absence of an α hydrogen.
o-hydroxy phenols are oxidized to o-quinones and p-hydroxy phenols to p-quinones. Such redox reactions involve the transfer of two electrons and two protons. The reversible redox property is crucial in...

Redox Reactions

Redox Reactions

Redox reactions are vital biochemical processes that underpin energy metabolism in cells. These reactions involve the transfer of electrons between molecules, occurring in tandem as oxidation and reduction. Oxidation refers to the loss of electrons, while reduction denotes their gain. This coupling ensures the seamless flow of electrons through metabolic pathways. For example, in bacterial metabolism, glucose undergoes oxidation to carbon dioxide, while oxygen is simultaneously reduced to...

Area of Science:

Parasitology
Biochemistry
Enzymology

Background:

Parasitic survival depends on combating host reactive oxygen and nitrogen species.
Peroxiredoxins (Prxs) are key enzymes in parasite defense mechanisms.
Understanding Prx systems in various parasites is crucial for developing new therapies.

Purpose of the Study:

To review the biochemistry, regulation, and cell biology of Prxs in parasitic protozoa, helminths, and fungi.
To address the current disarray in Prx nomenclature across different parasite species.
To introduce a systematic and informative naming convention for parasite Prxs.

Main Methods:

Literature review of existing research on parasite Prxs.
Analysis of parasite genome sequencing data to identify Prx players.
Development of a systematic nomenclature for Prx enzymes.

Main Results:

At least one Prx is present in all sequenced parasite genomes.
Common patterns in expression, localization, and function exist among related parasite Prxs.
A new, systematic nomenclature for parasite Prxs has been established to resolve confusion.

Conclusions:

The new Prx nomenclature facilitates comparative analysis and idea exchange within the research community.
Prxs represent promising targets for novel anti-parasitic therapies and vaccines.
Further exploration of Prx roles in diverse parasite systems is warranted for therapeutic advancement.
