“We now have the opportunity to ask whether a 21-amino acid form of life has an evolutionary advantage over life with 20 amino acids,” says the report’s lead author Peter Schultz, Ph.D ...

Recently, researchers in Japan investigated the role of a particular group of amino acids, known as D-amino acids, in the progression of viruses like influenza A virus (IAV) and SARS CoV-2 ...

Cholera bacteria use specific D-amino acids to escape unfavorable niches and form complex ecological systems. This is shown by a study led by a research group at Umeå University, Sweden.

The results unveiled a new role for D-amino acids in stress-driven bacterial chemotaxis. Using state-of-the-art technologies the researchers identified a previously uncharacterized chemoreceptor, ...
