  Cloning and Characterization of a Novel cDNA Sequence Encoding the Precursor of a Novel Venom Peptide (BmKbpp) Related to a Bradykinin-Potentiating Peptide from Chinese Scorpion Buthus martensii Karsch

  摘要：

  Based on the amino acid sequence of a bradykinin-potentiating peptide (Bpp) (peptide K-12) from scorpion Buthus occitanus, a full-length cDNA sequence encoding the precursor of a novel venom peptide (named BmKbpp) related to this Bpp, has been isolated and analyzed. The cDNA encodes a precursor of 72 amino acid residues, including a signal peptide of 22 residues and an extra Arg-Arg-Arg tail at the C-terminal end of the precursor which have to be removed in the processing step. The C-terminal region (21 residues) of the precursor is homologous (57% identical) with the sequence of peptide K-12, Thus, according to the primary structure of the BmKbpp precursor, there may be a propeptide between the signal peptide and the putative mature BmKbpp at the C-terminal region of the precursor.
