ACTION OF THE ANTIBIOTICS OF THE ITURIN GROUP ON ARTIFICIAL MEMBRANES

Abstract

The action of iturin A and bacillomycin L on vesicles of dipalmitoylphosphatidylcholine (DPPC) and DPPC-cholesterol was studied. Iturin A destroyed the vesicles, bacillomycin L bound with DPPC vesicles and destroyed vesicles containing DPPC and cholesterol. These results are discussed in comparison with the action of antibiotics of the Iturin group on cytoplasmic membranes.
