The phylogenetic relationships between the two southern hemisphere lamprey families (Geotriidae and Mordaciidae) and their northern hemisphere counterparts (Petromyzontidae) are unresolved. Insulin was isolated from an extract of islet-containing intestinal tissue from ammocoetes of the Australian lamprey, Mordacia mordax. Its primary structure was established as A-chain: GIVEQCCHRK10CSIYDMENYC20N and B-chain: SALMGTGGTH10LCGSHLVEAL20YVVCGQRGFF30 YTP[SKG]. Although the residues in parentheses are only tentatively assigned, mass spectrometry supports the proposed sequence and demonstrates that Mordacia proinsulin, unlike proinsulin from Geotria australis, is fully processed to mature insulin. Insulins from M. mordax and G. australis and from...
