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

Living organisms synthesize a staggering variety of proteins by combining 20 amino acids into chains of any length and order. In the past, to expand protein diversity beyond the scope of these 20 ...

Scientists trying to engineer biologic molecules with new functions have long felt limited by the 20 amino-acid building blocks. Researchers are working to develop ways of putting new building ...

Biologists have long known that amino acids can help stabilize proteins, for example as additives to pharmaceutical formulations. In trying to understand why this works, EPFL and MIT researchers have ...

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