Abstract
Two peptides with tachykinin-like ability to contract longitudinal muscle from the guinea pig ileum were isolated from the intestine of the common dogfish, Scyliorhinus caniculus. The amino acid sequence of scyliorhinin I was established as Ala-Lys-Phe-Asp-Lys-Phe-Tyr-Gly-Leu-Met-NH2 and this peptide cross-reacted with antisera directed against the C-terminal region fo substance P. The amino acid sequence of scyliorhinin II was established as Ser-Pro-Ser-Asn-Ser-Lys-Cys-Pro-Asp-Gly-Pro-Asp-Cys-Phe-val-Gly-Leu-Met-NH2 and this peptide cross-reacted with antisera directed against the C-terminal region of neurokinin A. The mammalian peptides substance P and neurokinin A were absent from the dogfish intestinal tissue.
