Abstract

The invention provides peptides which are particularly potent in stimulating the release of pituitary GH in fish and amphibians and which have a substantial portion or all of the following sequence: His-Ala-Asp-Gly-R.sub.5 -Phe-Asn-Lys-Ala-Tyr-Arg-Lys-Ala-Leu-Gly-Gln-Leu- Ser-Ala-Arg-Lys-Tyr-Leu-His-Thr-Leu-R.sub.27 -R.sub.28 -R.sub.29 -R.sub.30 -R.sub.31 -Gly-R.sub.33 -R.sub.34 -R.sub.35 -R.sub.36 -R.sub.37 - R.sub.38 -R.sub.39 -R.sub.40 -R.sub.41 -R.sub.42 -R.sub.43 -R.sub.44 -Ser wherein R.sub.5 is Met, Leu, Val, Nva, Gln, Thr, Ile or Nle; R.sub.27 is Met, Leu, Val, Nva, Gln, Thr, Ile or Nle; R.sub.28 is Ala, Ser or Asn; R.sub.29 is Lys or Arg; R.sub.30 is Arg or Gln; R.sub.31 is Val or Gln; R.sub.33 is Gly or Glu; R.sub.34 is Gly, Arg or Ser; R.sub.35 is Ser or Asn; R.sub.36 is Met, Leu, Val, Nva, Gln, Thr, Ile or Nle; R.sub.37 is Ile or Glu; R.sub.38 is Glu, Gln or Arg; R.sub.39 is Asp, Arg or Gly; R.sub.40 is Asp, Ser or Ala; R.sub.41 is Asn, Arg or Lys; R.sub.42 is Glu, Phe, Ala or Val; R.sub.43 is Pro, Asn or Arg; R.sub.44 is Leu or Ala. A sequence beginning at the C-terminus and extending part way or all the way to residue R.sub.27 may be deleted; a 29-residue peptide begi…
