| Glycine and valine exhibited isotopic values outside the range of our sampled end members. |
| Contents of alanine, valine, isoleucine, and leucine were increased by anaerobic conditions. |
| Branched-chain amino acids are composed of leucine, isoleucine and valine, three of 18 amino acids that make up a complete protein. |
| The formyl termini have been patched onto the last valine residue in the sequence of each monomer. |
