Vasoactive nonapeptide (RPPGFSPFR) formed by action of proteases on kininogens. Very similar to kallidin (which has the same sequence but with an additional N-terminal lysine). Bradykinin is a very potent vasodilator and increases permeability of post-capillary venules; it acts on endothelial cells to activate phospholipase A2. It is also spasmogenic for some smooth muscle and will cause pain.
Bradykinin is a peptide that causes blood vessels to dilate (enlarge), and therefore causes blood pressure to fall. A class of drugs called ACE inhibitors, which are used to lower blood pressure, increase bradykinin (by inhibiting its degradation) further lowering blood pressure. Bradykinin dilates blood vessels via the release of prostacyclin, ni...Found on http://en.wikipedia.org/wiki/Bradykinin
(brad″e-ki´nin) a nonapeptide kinin formed from a plasma protein, high-molecular-weight (HMW) kininogen by the action of kallikrein; it is a very powerful vasodilator that increases capillary permeability and, in addition, constricts smooth muscle and stimulates pain receptors.Found on http://www.encyclo.co.uk/local/21001
