These are published properties of the molecule, given for identification. Values we cannot confirm are omitted rather than estimated. What these terms mean.
What this compound is
Twelve residues. Another member of the same family, ending in the shared five-residue motif.
Sequence
| 1 | DVPKSDQFVG LM |

- Three-letter code
- Asp-Val-Pro-Lys-Ser-Asp-Gln-Phe-Val-Gly-Leu-Met
The one-letter code gives the amino-acid backbone. Terminal modifications, where a compound carries them, are accounted for in the molecular weight above but are not visible in the letters.
Residue composition
Counted directly from the sequence above. Kassinin is built from 10 of the twenty standard amino acids across 12 positions.
