A machine-learning model computationally breaks down how segments of amino acid chains determine a protein's function, which could help researchers design and test new proteins for drug development or ...

With a newly developed method that compares AI-generated protein sequences with naturally occurring ones, function- and structure-regulating amino acids can be determined much more precisely than ...

D-serine is a representative D-form amino acid and has crucial roles in mammals, but its role in non-mammals is unclear. Researchers from Japan recently uncovered a functional role of D-serine in a ...

Mutations can occur on several levels, including genetic, but can also take the form of amino acid replacements during protein synthesis. Amino acid replacements can be deleterious, neutral, or ...

In mice, limited intakes of one specific essential amino acid can slow the effects of aging and even extend their lifespan, research from the US shows. Scientists wonder if these findings could help ...

5-hydroxytryptophan (5-HTP) is a naturally occurring amino acid and the essential precursors of serotonin (5-hydroxytryptamine) an important neurotransmitter for mood regulation, memory, learning, and ...
