Abstract

The proposed amino acid sequence of porcine LH- and FSH-releasing hormone (LH-RH/FSH-RH) was reinvestigated by Edman-dansyl degradation after the cleavage of N-terminal pyroglutamyl residue by pyrrolidonecarboxylyl (PCA) peptidase. A C-terminal fragment from chymotrypic digest of LH-RH/FSH-RH was found to be identical to synthetic Gly-Leu-Arg-Pro-Gly-NH₂. The results indicate that the structure initially proposed is correct. The amino acid sequence of porcine LH-RH/FSH-RH is thus (pyro)Glu-His-Trp-Ser-Tyr-Gly-Leu-Arg-Pro-Gly-NH₂.
