Proteins form the structural and functional backbone of the cell, and any perturbation in their synthesis can disrupt normal ...

Amino acids are joined together by peptide bonds to form polypeptide chains. The sequence of amino acids in a protein, known as its primary structure, is determined by the genetic code. This sequence ...

Two papers in Science now provide structural insights into these processes, and also give a first glimpse of the structure of the conserved polypeptide-transport-associated (POTRA) domain.
