| The active site of the homodimeric HIV-1 protease includes six amino acids. |
| Variation in individual samples is high, and quantitative analysis of amino acids from fossils of this age has no value for taxonomy. |
| The leader transcript contains an open reading frame which encodes a polypeptide of 44 amino acids. |
| There they are converted to fatty acids, amino acids, and glycogen, or else oxidized by the various catabolic pathways of cells. |
| Precipitation of a peptide in the top agar with subsequent release of amino acids can also lead to confounding results. |
| During normal catabolism, protease enzymes break down carboxylase enzymes and reclaim the associated amino acids and biocytin for recycling. |
