Researchers from ETH Zurich have modified a bacterial transport system so that it can efficiently introduce large quantities of unnatural amino acids into cells, disguised as a kind of Trojan horse.

Although the myriad proteins found in all life are largely built from a set of 20 amino acids, many other amino acids exist in nature, and it remains a curiosity as to why some were ultimately ...

The genetic code is the recipe for life, and provides the instructions for how to make proteins, generally using just 20 amino acids. But certain groups of microbes have an expanded genetic code, in ...

Researchers have engineered bacteria to synthesize an amino acid that contains a rare functional group that others have shown to have implications in the regulation of our immune system. The ...

The 20 amino acids that make up the building blocks of a protein contain chemical bonds that vibrate at different frequencies. Markus Buehler, a materials scientist and engineer at the Massachusetts ...

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, ...

Researchers demonstrated how amino acids could spontaneously attach to RNA under early Earth-like conditions using thioesters, providing a long-sought clue to the origins of protein synthesis. This ...
