Edman Sequencing

The dorsal glandular extract of the toadlet Uperoleia mjobergii contains more than 20 peptides. We report the amino acid sequences of the seven major peptides: these were determined by a combination of mass spectrometry and automated Edman sequencing. Three of these peptides have 19 amino acid residues and belong to the uperin 2 group of peptides [e.g. uperin 2.6, Gly Ile Leu Asp Ile Ala Lys Lys Leu Val Gly Gly Ile Arg Asn Val Leu Gly Ile (OH)], while the other four have 17 residues and are classified as uperins 3 [e.g. Uperin 3.4, Gly Val Gly Asp Leu Ile Arg Lys Ala Val Ala Ala Ile Lys Asn Ile Val (NH2)]. Several of these cationic peptides have been synthesized in order for bioassays to be carried out: they show significant antibiotic activity against a range of Gram-positive microorganisms. A major skin peptide from the related species Uperoleia inundata is a powerful neuropeptide named uperin 1.1 ([Ala2] uperolein ): no corresponding neuropeptide is detected in the skin glands of Uperoleia mjobergii.

And Function

Bandicoots (Marsupialia : Peramelidae) of the genera Isoodon, Perameles and Macrotis possess either subauricular or interauricular cephalic skin gland complexes. The pig-footed bandicoot Chaeropus is the only genus apparently lacking cephalic skin glands. Skin gland complexes consist of enlarged sebaceous acini and sudoriferous tubules. though the latter are less apparent in Macrotis than the other genera. The surface of the gland complex has a pockmarked appearance with a small depression surrounding each guard hair shaft. The complex increases in activity very markedly during the breeding season in both sexes. but particularly in males. The most noticeable aspect of the pre-breeding hypertrophy is an expansion of the sebaceous element, which presses the sudoriferous element down into the deeper layers of the dermis. It is suggested that the pungent odour secreted by these complexes plays a calming and reassuring role in the courtship behaviour of these solitary and pugnacious small marsupials.
