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

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, ...

To ensure that protein production in our cells runs smoothly, the protein complex NAC slows down the rate of protein ...

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 ...

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 ...

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 ...

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 ...

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.

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 ...

Researchers from ETH Zurich have succeeded in introducing large quantities of unnatural amino acids into bacteria, enabling ...
