Structural characterization of a 40 amino acid peptide with high intrinsic growth hormone releasing activity isolated from a human pancreatic tumor which had caused acromegaly was accomplished by gas phase sequence analyses of the intact peptide and its carboxy terminal cyanogen bromide digestion fragment. High pressure liquid chromatography of the native peptide and synthetic replicates showed that the molecule possessed a free acid rather than an amidated carboxy terminus. The structure of the peptide was established as: Tyr-Ala-Asp-Ala-Ile-Phe-Thr-Asn-Ser-Tyr-Arg-Lys- Val-Leu-Gly-Gln-Leu-Ser-Ala-Arg-Lys-Leu-Leu-Gln-Asp-Ile-Met-Ser-Arg-Gln-Gln-Gly- Glu-Ser-Asn-Gln-Glu-Arg-Gly-Ala-OH using 1.8 nmoles of material. The structural identity of this material with a previously characterized fragment of a larger growth hormone releasing peptide isolated from a different human tumor is discussed.
