Bradykinin-potentiating peptides fromEchis multisquamatus venom

Eight bradykinin potentiating peptides have been isolated in the pure form from the low-molecular-mass fraction of the venom of the Central Asian viper Echis multisquamatus Ch. The peptides isolated differed in the efficacy of their bradykinpotentiating activity and their capacity for inhibiting the angiotensin-converting enzyme (ACE, EC 3.4.15.1); however, complete correlation of the two activities was established for only six of them.
