CHAMPAIGN, Ill. -- Components in grapes, including some newly identified ones, work together to dramatically inhibit an enzyme crucial to the proliferation of cancer cells, say scientists at the ...

Extracts from plant chloroplasts and algae catalyze the conversion of glutamate to δ-aminolevulinic acid (ALA) in the first committed step of the tetrapyrrole biosynthetic pathway leading to ...

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, ...

Figure 1: Assembly of hexagon-like DNA strips and their structural imaging. We found by fluorescence measurements in solution and confocal fluorescence microscopy analyses on surfaces that FRET ...

Imagine trying to bake a cake without heat. You’ve got all the ingredients like flour, eggs and sugar, but nothing is happening. That’s what your body would be like without enzymes: potential but no ...

Plant cell wall components such as cellulose are abundant sources of carbohydrates that are widely used in biofuels and bioproducts; however, extraction of these components from plant biomass is ...

Enzymes are amazing catalysts. These proteins are made of nothing more than a handful of Earth-abundant elements, and they promote a vast array of reactions, convert chemical energy to physical motion ...

A newly identified protein and other proteins it interacts with could become effective targets for new drugs to control the parasite that cause toxoplasmosis, researchers reported. A newly identified ...

Liver enzymes can fluctuate due to factors like hormonal changes or reactions to medications. Fluctuations are often temporary, but long-term changes may indicate a condition that requires medical ...
