RT   Protonectarina sylveirae (Hymenoptera-Vespidae).";
RL   Nat. Toxins 1:271-276(1993).
CC   -!- FUNCTION: Potent antimicrobial peptide against both Gram-positive and
CC       Gram-negative bacteria (By similarity). This hemolytic peptide shows
CC       potent histamine releasing activities on rat peritoneal mast cells.
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC   -!- SIMILARITY: Belongs to the MCD family. Mastoparan subfamily.
CC       {ECO:0000305}.
