CC   -!- FUNCTION: Antimicrobial peptide, active against the Gram-negative
CC       bacterium E.coli K12-594 (MIC=3.12 ug/ml), the Gram-positive bacteria
CC       B.subtilis KCTC 3086 (MIC=3.12 ug/ml), S.aureus KCTC 1928 (MIC=25
CC       ug/ml) and M.luteus KCTC 3063 (MIC=1.56 ug/ml), the antibiotic
CC       resistant bacteria methicillin-resistant S.aureus (MRSA) (MIC=25 ug/ml)
CC       and vancomycin-resistant Enterococci (VRE) (MIC=25 ug/ml), and the
CC       fungi C.albicans KCTC 7965 (MIC=50 ug/ml) and C.tropicalis KCTC 1925
CC       (MIC=3.12 ug/ml). Has very low hemolytic activity on rat erythrocytes.
