Redox regulation in chloroplasts is a fundamental process that ensures the optimal performance of photosynthesis through the reversible modification of key enzymes. Central to this mechanism is the ...

Enzymes help with specific functions that are vital to the operation and overall health of the body. They help speed up chemical reactions in the human body. They are essential for respiration, ...

A network of enzymatic and nonenzymatic antioxidants protects chloroplasts from photooxidative damage. With all enzymatic components being nuclear encoded, the control of the antioxidant capacity ...

Enzymes are biological molecules that play a crucial role in various biochemical reactions within living organisms. They act as catalysts, which means they speed up the rate of chemical reactions ...

A new paper reports a truly radical development: Researchers designed a metalloprotein that can stabilize a reactive organic radical that is not normally stable in water. The work is a first step ...

A new model of the active site of a key enzyme in cellular respiration allows scientists to study the enzyme under conditions where the flow of electrons is the limiting step, as it is in the natural ...

Throughout evolution, pathogenic microorganisms, such as bacteria, viruses, and fungi, have developed sophisticated defense strategies to survive and multiply in the hostile environment of their hosts ...
