From: Looking for the bird Kiss: evolutionary scenario in sauropsids
Amino-acid sequences of Kisspeptin 10 (Kp(10)) and their proteolytic and alpha-amidation sites from various vertebrates, including novel predicted sequences from sauropsids. Amino acids are coloured according to their physico-chemical properties. The C-terminal GKR motif represents the typical proteolytic and alpha-amidation site. Striking substitutions in bird and crocodilian sequences are highlighted by white background.
