Two glucagon-like peptides have been isolated from guinea pig pancreas and their primary structures determined. A 29-residue peptide is identical to the glucagons from all other mammals yet studied in the N-terminal region (residues 1-20) but the C-terminal region [Gln-Phe-Leu-Lys-Trp-Leu-Leu-Asn-Val] contains five substitutions. A 37-residue peptide probably represents guinea pig glucagon extended from the C-terminus by [Lys-Arg-Asn-Arg-Asn-Asn-Ile-Ala] and is analogous to human oxyntomodulin (glucagon-37). The structures suggest evolutionary pressure to conserve the N-terminal region of glucagon and the C-terminal region of oxyntomodulin. The biological activity of guinea pig glucagon has not yet been determined but it is speculated that changes in the C-terminal region of glucagon may have produced a molecule with reduced biological potency that is appropriate to the reduced potency of guinea pig insulin.
