Methionine is an amino acid that is used to build molecules important for cell and DNA function. Meat, eggs, fish, and other foods containing protein will have some methionine in them. Amino acids ...

A machine-learning model from MIT researchers computationally breaks down how segments of amino acid chains determine a protein’s function, which could help researchers design and test new proteins ...

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 ...

All the cells of an organism contain a copy of DNA in their nucleus. In order to implement the instructions it contains, this DNA must be copied into an RNA molecule, which reaches the ribosomes, ...

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 ...

A new method to image intracellular fatty acids at a single cell level has been developed by a team of researchers. They treated cells with fatty acids containing a single bromine atom and used ...
