Accepted January 17, 2002
Insulin was purified from pancreatic extracts of two elas-
mobranch species belonging to different families in
the order Carcharhiniformes, the European spotted
dogfish, Scyliorhinus canicula (Scyliorhinidae), and the
hammerhead shark, Sphyrna lewini (Carcharhinidae).
The amino acid sequence of dogfish insulin was estab-
lished as A-chain GIVDHCCRNT10
CSLYDLEGYC20
NQ and
B-chain LPSQHLCGSH10
