CC -!- FUNCTION: Maximin-10 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-H3 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}.
CC -!- SUBCELLULAR LOCATION: Secreted.
CC -!- TISSUE SPECIFICITY: Expressed by the skin glands.
CC -!- MASS SPECTROMETRY: [Maximin-H3]: Mass=1944; Method=FAB;
CC Evidence={ECO:0000269|PubMed:11835991};
CC -!- SIMILARITY: Belongs to the bombinin family. {ECO:0000305}.
