RT   antimicrobial peptides in the splendid leaf frog, Cruziohyla calcarifer.";
RL   J. Proteomics 146:1-13(2016).
CC   -!- FUNCTION: Has antimicrobial activity against Gram-negative bacterium
CC       E.coli (MIC=26.35 uM), aginst Gram-positive bacterium S.aureus
CC       (MIC=6.59 uM) and against fungus C.albicans (MIC=13.18 uM). At higher
CC       concentrations also has a bactericidal and fungicidal effect. Has
CC       hemagglutinating activity against horse erythrocytes.
