Figure 1.
(a) cDNA-encoded biosynthetic precursors are identified from skin secretion of Bombina maxima; (b) cDNA-encoded biosynthetic precursors are identified from skin secretion of Bombina orientalis and Bombina variegate. BOK and BVK represent preprobradykinin kininogens from Bombina orientalis and Bombina variegate, respectively. The putative signal peptide sequences are shown in italic typeface and the mature peptide sequences are represented in bold typeface. The access numbers are shown after the name of each precursor.
