The structure of a toxic octapeptide from the larvae of sawfly
Abstract
The amino acid sequence of an octapeptide from sawfly (Lophyrotoma interrupta) larvae, which acts as a liver toxin, has been determined as C6H5COAla–Phe–Val–Ile–Asp–Asp–Glu–Gln. The amino acids, Ala, Phe, Asp5, and Glu7 residues, have the D absolute configuration.
