IUPAC Name: (2S)-2-[[(2S)-2-[[(2S)-1-[(2S)-2-[[(2S)-2-[[2-[[(2S)-1-[(2S)-1-[(2S)-2-amino-5-(diaminomethylideneamino)pentanoyl]pyrrolidine-2-carbonyl]pyrrolidine-2-carbonyl]amino]acetyl]amino]-3-phenylpropanoyl]amino]-3-hydroxypropanoyl]pyrrolidine-2-carbonyl]amino]-3-phenylpropanoyl]amino]-5-(diaminomethylideneamino)pentanoic acid

Description: The molecule is a linear nonapeptide messenger belonging to the kinin group of proteins, with amino acid sequence RPPGFSPFR. Enzymatically produced from kallidin in the blood, it is a powerful vasodilator that causes smooth muscle contraction, and may mediate inflammation. It has a role as a human blood serum metabolite and a vasodilator agent. It is a tautomer of a bradykinin(2+).
