Summary
Researchers discovered mannosyltransferase/phosphorylases (MTPs) that control mannogen synthesis and degradation in Leishmania parasites. These MTPs are potential drug targets due to mannogen
Area of Science:
- Parasitology
- Biochemistry
- Molecular Biology
Background:
- Leishmania parasites utilize unique storage carbohydrates called mannogens.
- The enzymes responsible for mannogen metabolism were previously unknown.
Purpose of the Study:
- To identify and characterize the enzymes involved in mannogen synthesis and degradation in Leishmania.
- To explore the potential of these enzymes as drug targets.
Main Methods:
- Enzyme assays to study mannosyltransferase/phosphorylase (MTP) activity.
- Genetic manipulation of Leishmania parasites to investigate MTP function.
- Analysis of mannogen levels under different conditions.
Main Results:
- A novel family of mannosyltransferase/phosphorylases (MTPs) was discovered.
- MTPs are crucial for both mannogen synthesis and degradation.
- Mannogen plays a key role in regulating carbon metabolism and parasite virulence.
Conclusions:
- The newly discovered MTPs are essential regulators of mannogen metabolism in Leishmania.
- MTPs represent promising therapeutic targets for treating Leishmania infections.

01:15Metabolism of Chemolithotrophs
691
Chemolithotrophs are microorganisms that obtain energy by oxidizing inorganic molecules such as hydrogen gas (H₂), ammonia (NH₃), reduced sulfur compounds (H₂S, S²⁻), and ferrous iron (Fe²⁺). Unlike heterotrophic organisms that rely on organic carbon, chemolithotrophs transfer electrons from these inorganic donors to the electron transport chain (ETC), generating a proton motive force (PMF) that drives ATP synthesis through oxidative phosphorylation.

Living cells constantly carry out various chemical reactions which are necessary for their proper functioning. These reactions are interlinked to one another via multiple pathways. The collection of these chemical reactions is known as metabolism.
Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...

Triglycerides serve as crucial long-term energy storage molecules in microorganisms, providing a dense source of metabolic energy. Their breakdown is mediated by lipases, which hydrolyze triglycerides into glycerol and free fatty acids. Each of these components follows distinct metabolic pathways, ultimately contributing to ATP synthesis and cellular energy homeostasis.Glycerol MetabolismGlycerol, released from triglyceride hydrolysis, is phosphorylated by glycerol kinase to form...

Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Amino acid biosynthesis is essential for cell growth, protein synthesis, and metabolic regulation. Cells generate essential and non-essential amino acids from metabolic intermediates to sustain vital biological functions. These intermediates originate from key metabolic pathways: glycolysis, the tricarboxylic acid (TCA) cycle, and the pentose phosphate pathway. Important precursors include α-ketoglutarate, pyruvate, oxaloacetate, phosphoenolpyruvate, and erythrose-4-phosphate, which...

8.9K
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...
