Abstract

The sturgeons (order Acipenseriformes) are extant representatives of a group of ancient Actinopterygian (ray-finned) fish. Galanin and scyliorhinin I(a tachykinin with limited structural similarity to mammalian substance P)have been isolated from an extract of the gastrointestinal tract of a sturgeon (an F1 hybrid between the shovelnose sturgeon, Scaphirhynchus platorynchus, and the pallid sturgeon, Scaphirhynchus albus). The primary structureof sturgeon galanin (Gly-Trp-Thr-Leu-Asn-Ser-Ala-Gly-Tyr-Leu(10)-Leu-Gly-Pro-His-Ala-Val-Asp-Gly-His-Arg(20)-Ser-Leu-Ser-Asp-Lys-His-Gly-Leu-Pro.NH2)contains only two amino acid substitutions (Ser(23) --> Asn and Pro(29) -->Ala) compared with galanin from the bowfin, Amia calva (Amiiformes), but five amino acid substitutions compared with galanin from the trout (Teleostei). Similarly, the sturgeon tachykinin (Ser-Lys-Tyr-His-Gln-Phe-Tyr-Gly-Leu-Met.NH2) contains only one amino acid substitution (Tyr(3) --> Ser) compared with scyliorhinin I previously isolated from bowfin stomach but five amino acid substitutions compared with trout substance P. The data support thehypothesis that the Acipenseriformes and the basal Neopterygians (gars andbowfin) share a close phylogenetic relationship. (C) 1999 Academic Press.
