Inside our cells, ribosomes—the tireless "protein factories" of life—have just shown off a new skill they haven't used in ...

Every basic biology lesson teaches that proteins are made up of combinations of 20 distinct amino acids, which are ordered in various patterns similar to words.

Scientists have shown that bacterial ribosomes can incorporate cyclic beta amino acids into polypeptides. By expanding the set of monomers that nature’s translation machinery is understood to work ...

Pyr (also called pyroglutamate) is a cyclic amino acid formed as a result of dehydration of glutamate. All proteins consist of multiple amino acids joined together by peptide bonds, with ...

This cyclic amino acid appears in other known antibiotics, but the enduracyclinones look different from those molecules, says Margaret Brimble of Auckland University, an expert in bioactive ...

In a new peer reviewed analysis, scientists quantify amino acids before and after our “last universal common ancestor.” The last universal common ancestor is the single life form that branched ...

A paper about the work, “Ribosome-mediated polymerization of Long-carbon Chain and Cyclic Amino Acids into Peptides In Vitro” was published August 27 in the journal Nature Communications.

An amino acid has been produced in a lab by warming analogs of ices found in the freezing conditions of interstellar gas clouds.

Between protein powder, amino acids, and creatine, there are a lot of performance supplements for athletes. Nutritionists explain which ones are backed by science.

Scientists have taken a big step towards figuring out where building blocks of life such as amino acids and amines form in space.
