CC   -!- FUNCTION: M-poneritoxin-Dq4b: this synthetic peptide has antimicrobial
CC       activity against Gram-positive bacteria B.amyloliquefacies S499
CC       (MIC=0.1 mM), L.monocytogenes 2231 and S.aureus ATCC 29213, against
CC       Gram-negative bacteria P.putida BTP1, P.aeruginosa PaO1 and E.coli ATCC
CC       10536, and against the fungi S.cerevisiae, R.mucilaginosa and
CC       C.cucumerinum. Not active against the fungi F.oxysporum and B.cinerea.
