CC   -!- FUNCTION: Antimicrobial peptide active against many Gram-negative
CC       enterobacterial and plant-associated bacterial species. Not active
CC       against other bacterial species like H.pylori, P.mirabilis, B.pertussis
CC       or N.gonorrhoeae. {ECO:0000269|PubMed:7929322}.
CC   -!- FUNCTION: [Apidaecin Yj +S]: Not active against Y.enterolytica or
CC       A.tumefaciens. {ECO:0000269|PubMed:7929322}.
CC   -!- FUNCTION: [Apidaecin Yj -S]: Among others, also active against
CC       Y.enterolytica and A.tumefaciens. {ECO:0000269|PubMed:7929322}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:7929322}.
CC   -!- INDUCTION: By bacterial infection. {ECO:0000269|PubMed:7929322}.
CC   -!- MASS SPECTROMETRY: [Apidaecin Yj +S]: Mass=2102.9; Method=MALDI;
CC       Note=Apidaecin Yj +S.; Evidence={ECO:0000269|PubMed:7929322};
CC   -!- MASS SPECTROMETRY: [Apidaecin Yj -S]: Mass=2015.8; Method=MALDI;
CC       Note=Apidaecin Yj - S.; Evidence={ECO:0000269|PubMed:7929322};
CC   -!- SIMILARITY: Belongs to the apidaecin family. {ECO:0000305}.
