Hidden within the genetic code lies the "triplet code," a series of three nucleotides that determine a single amino acid. How did scientists discover and unlock this amino acid code? Once the budding ...

The findings, which detail how amino acids shaped the genetic code of ancient microorganisms, shed light on the mystery of how life began on Earth. "You see the same amino acids in every organism, ...

Using quantum chemical methods, a team of researchers led by Dr. Matthias Granold and Professor Bernd Moosmann of the Institute of Pathobiochemistry at Johannes Gutenberg University Mainz solved one ...

With only rare exceptions, every organism constructs proteins from just 20 building blocks called amino acids. Recently, however, researchers modified Escherichia coli bacteria so that the ...

A new study finds that at least one Archaea has surprisingly flexibility when interpreting genetic code, which goes against a ...

Scientists at The Scripps Research Institute (TSRI) report in an upcoming article in the Journal of the American Chemical Society their synthesis of a form of the bacterium Escherichia coli with a ...

Biochemists shed light on the evolution of our 20- amino acid toolbox. The genetic code of life depends mainly on 20 amino acids, which can be arranged in various combinations to form proteins. For ...

Proteins are among the most important molecular building blocks of life. They are chains of amino acids assembled in our cells by ribosomes, the molecular "protein factories" of our bodies. The ...

Humans possess six forms of the protein actin, which perform essential functions in the body. Two in particular, ?-actin and ?-actin, are nearly identical, only differing by four amino acids. Yet ...

Membrane proteins play important roles in health and disease, but they are so hydrophobic that they require detergents to maintain their shape outside membranes. That makes them difficult to study.

Amino acids are the building blocks of protein. These molecules come together to form proteins. Your body uses them for many important functions, such as making hormones, building muscle, and ...
