Pa. Grigoriev et al., DIFFERENCES IN ION PERMEABILITY OF AN ARTIFICIAL BILAYER-MEMBRANE CAUSED BY AMPULLOSPORIN AND BERGOFUNGIN, NEW 15-MEMBERED PEPTAIBOL-TYPE ANTIBIOTICS, Bioelectrochemistry and bioenergetics, 44(1), 1997, pp. 155-158
The membrane activity of new 15-membered peptaibol-type antibiotics, a
mpullosporin (I) from Sepedonium ampullosporum and bergofungin (II) fr
om Emericellopsis donezkii, was tested by use of an artificial bilayer
membrane, Bergofungin (II) conveys protons more efficiently than ampu
llosporin (I) suggesting that the-nature and the sequence of the const
ituting amino acids determine their special effect on ion penetration.
