Abstract

The structure of the bradykinin potentiating peptide component BPP1 from a 70% methanol extract of the lyophilized powder of pit viper from Zhejiang Province is shown as follows: (formula see text) When the pyroglutamyl residue was removed by pyroglutamate aminopeptidase, the activity of BPP1 was enhanced two-fold but decreased gradually during the course of Edman degradation. The above facts show that the structure integrity of the C-terminal is absolutely necessary for the activity of BPP1.
