Researchers discover a unique genetic code in Antarctic archaea that encodes a rare amino acid, potentially advancing protein ...

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 ...

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 ...

LA JOLLA, CA - In recent years, scientists have engineered bacteria with expanded genetic codes that produce proteins made from a wider range of molecular building blocks, opening up a promising front ...

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 ...

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 ...

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, ...
