It has an anomalous deuterium signature that indicates non terrestrial origin.

Interesting, but they are stretching the truth. They have found Amino acid polymer, not protein, consisting of ~20 amino acids. To start with it is too small to be a protein, only 2.3 kDa. Also, the way how amino acid residues are connected is fundamentally different from a protein. Looks more like a cyclic peptide. Interesting organic molecule nevertheless.

Thanks for the observation. I'm a crappy organic chemist. :shrug: So thanks for pointing that out!
