Results about: proteins

A high resolution description of the structure and dynamics of proteins is a very useful tool to study the properties and the function of these important biomacromolecules and, most importantly, to understand how changes in sequence or environment can lead to disease.

Our research focuses on three angles of peptide and protein chemistry : the design, synthesis and structure of bioactive molecules. From a structural perspective, we apply modern NMR techniques to study complex molecular recognition processes.

Discovery of a fundamental limit to the evolution of the genetic code

A study performed at IRB Barcelona offers an explanation as to why the genetic code, the dictionary used by organisms to translate genes into protein, stopped growing 3,000 million years ago.

The reason is attributed to the structure of transfer RNAs—the key molecules in the translation of genes into proteins.

The genetic code is limited to 20 amino acids—the building blocks of proteins—the maximum number that prevents systematic mutations, which are fatal for life.

The discovery could have applications in synthetic biology.
