What is it about?

Polypeptides are synthesized by a condensation reaction between amino acids. We found that this important reaction is catalyzed by mineral oxide surfaces, even if these minerals do not have any specific catalytic sites.

Why is it important?

Our discovery can help to set up a viable and economically convenient route for the industrial production of short polypeptides.


Our findings may help to understand if minerals may have played a role in the formation of peptides in the prebiotic era. Besides this fascinating possibility, the fact that catalysis occurs on the most abundant portions of anatase nanoparticles may foster the use of these materials as environmentally-friendly catalysts for the production of oligopeptides
