CC   -!- FUNCTION: Maximin-11 shows antimicrobial activity against bacteria and
CC       against the fungus C.albicans. It has little hemolytic activity (By
CC       similarity). {ECO:0000250}.
CC   -!- FUNCTION: Maximin-H1 shows antibacterial activity against both Gram-
CC       positive and Gram-negative bacteria. It shows also antimicrobial
CC       activity against the fungus C.albicans. Shows strong hemolytic
CC       activity. {ECO:0000269|PubMed:11835991, ECO:0000269|Ref.2}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|Ref.2}.
CC   -!- TISSUE SPECIFICITY: Expressed by the skin glands. {ECO:0000269|Ref.2}.
CC   -!- MASS SPECTROMETRY: [Maximin-H1]: Mass=1933; Method=FAB;
CC       Evidence={ECO:0000269|PubMed:11835991};
CC   -!- SIMILARITY: Belongs to the bombinin family. {ECO:0000305}.
