Azioni biochim/fisiol

Syringomycin E (SR-E) is a phytotoxin of the cyclic lipodepsinonapeptides class composed of a 3-hydroxy fatty acid tail attached to a polar peptide head that contains nine amino acid residues. SR-E is a potent biosurfactant, which is toxic to many plants and fungi and is implicated as a virulence factor in several major plant diseases such as holcus spot disease of maize and bacterial canker of stone fruits. Syringomycin E inhibits the growth of several yeast strains including Rhodotorula pilimanae and Saccharomyces cerevisiae and is also effective against human pathogenic fungi. Syringomycin E targets the plant and fungal plasma membrane altering several of its functions such as membrane potential, protein phosphorylation, H+-ATPase activity, and ion fluxes. All of these effects are related to SR-E pore formation in the host membrane. At least six molecules of syringomycin E compose a channel with a radius of ~1 nm and individual channels can become aggregated into clusters that exhibit synchronous opening and closing. Remarkably, the host membrane composition influences the sensitivity to syringomycin E and membrane lipids directly participate in the channel gating. Syringomycin E is reported to cause lysis of erythrocytes of different origin.
