RT   cuprea: purification, amino acid sequences and antibacterial activity.";
RL   Insect Biochem. Mol. Biol. 32:75-84(2001).
CC   -!- FUNCTION: Antibacterial protein. Strong activity against the Gram-
CC       positive bacteria M.luteus, B.megaterium and S.aureus. Reduced activity
CC       against Gram-positive bacterium B.subtilis and weak activity against
CC       Gram-negative bacterium X.japonicus. No detectable activity against the
CC       Gram-negative bacteria E.asbriae, E.coli, P.aeruginosa and
CC       S.marcescens. {ECO:0000269|PubMed:11719071}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000255|PROSITE-ProRule:PRU00710,
CC       ECO:0000269|PubMed:11719071}.
CC   -!- MASS SPECTROMETRY: Mass=4433.1; Method=MALDI;
CC       Evidence={ECO:0000269|PubMed:11719071};
CC   -!- SIMILARITY: Belongs to the invertebrate defensin family. Type 1
CC       subfamily. {ECO:0000255|PROSITE-ProRule:PRU00710}.
