Larger Image Figure 3. Primary structures of the caerulein precursor fragment (CPF) peptides isolated from skin secretions of frogs belonging to the genera Xenopus and Silurana. a denotes C-terminal α-amidation. In order to maximize structural similarity, gaps denoted by * have been introduced into some sequences. Strongly conserved residues are shaded.
