Scientists explore the creation of artificial organelles

Cells have small compartments known as organelles that perform complex biochemical reactions. These compartments have multiple enzymes that work together to execute important cellular functions. Researchers at the Center ...

Structure of the enzyme behind the world's smallest turbine, solved

The chemical ATP, adenosine triphosphate, is the fuel that powers all life. Despite ATP's central role, the structure of the enzyme generating ATP, F1Fo-ATP synthase, in mammals, including humans, has not been determined. ...

Oldest enzyme in cellular respiration isolated

In the first billion years, there was no oxygen on Earth. Life developed in an anoxic environment. Early bacteria probably obtained their energy by breaking down various substances by means of fermentation. However, there ...

Control of a mitochondrial protective mechanism identified

Mitochondria are essential for normal functioning of almost all cells, since they are the main production sites of the energy-carrying molecule adenosine triphosphate (ATP). In addition, mitochondria are the key sites of ...

Biophysicists find 'extra' component in molecular motor

Researchers from the Moscow Institute of Physics and Technology have discovered an additional component in ATP synthase, a molecular machine that produces the energy-conserving compound in all cellular organisms. The new ...

New metabolic pathway discovered in rumen microbiome

Cows can adapt themselves to a fluctuating sodium content in their feed. How they do that was so far a secret. Researchers from Goethe University have now discovered a bacterium in the microbiome of the rumen which has a ...

Structure of a mitochondrial ATP synthase

ATP synthase is a universal molecular machine for energy conversion. By coupling to cellular respiration in mitochondria, it catalyzes conversion of chemical energy of cells.

Scientist constructs artificial photosynthetic cells

A team led by associate professor Yutetsu Kuruma of the Earth-Life Science Institute (ELSI) at Tokyo Institute of Technology has constructed simple artificial cells that can produce chemical energy that helps synthesize parts ...
