Feleucins‐BV1 and ‐BV2 are recently described prototypes of a novel antimicrobial non‐apeptide (AMP) family identified in the skin secretion of the bombinid toad, Bombina variegata. They are encoded on different precursors that also encode a novel bombinin. Here we describe the identification of feleucin‐BO1 (FLGLLGSLLamide) which is co‐encoded with a different novel bombinin, named feleucin precursor‐associated...
While bradykinin has been identified in the skin secretions from several species of amphibian, bradykinin-related peptides (BRPs) are more common constituents. These peptides display a plethora of primary structural variations from the type peptide which include single or multiple amino acid substitutions, N- and/or C-terminal extensions and post-translational modifications such as proline hydroxylation...
Amphibian skin secretions are unique sources of bioactive peptides and their donor species are currently rapidly disappearing from the biosphere. Here, we report that both peptides and polyadenylated mRNAs from skin granular glands remain amenable to study in samples of stimulated skin secretions following their storage in 0.1 % aqueous trifluoroacetic acid at −20 °C for many years. Frozen acidified...
