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 ...

Humans possess six forms of the protein actin, which perform essential functions in the body. Two in particular, ?-actin and ?-actin, are nearly identical, only differing by four amino acids. Yet ...

ADP-ribosylation is an ancient post-translational modification found in viruses, bacteria and eukaryotes 1. It is catalyzed by members of the ART superfamily of proteins, which transfer ADPr from ...

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 ...

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 ...

Phenylalanine is an amino acid in plant and animal foods, such as meat, eggs, fish, and soy products. It is safe for most people, except for those with phenylketonuria, who may not be able to break it ...

Plant Physiology, Vol. 146, No. 3 (Mar., 2008), pp. 1028-1039 (12 pages) In Arabidopsis thaliana, transamination steps in the leucine biosynthetic and catabolic pathways and the methionine (Met) chain ...
