Amino acids are the fundamental building blocks of proteins and play central roles as intermediates in myriad metabolic pathways. In medical biochemistry, they are not only recognised for their ...

Biochemists shed light on the evolution of our 20- amino acid toolbox. The genetic code of life depends mainly on 20 amino acids, which can be arranged in various combinations to form proteins. For ...

The molecular machines that cells use to build proteins are backed by a billion years of evolution. In that time, these machines—ribosomes—have become exceptionally good at forging amide bonds between ...
