Application

Syringomycin E from Pseudomonas syringae may be used in proton pumps and membrane potential studies.

Biochem/physiol Actions

Phytotoxin of the cyclic lipodepsinonapeptides class. Potent biosurfactant, which is toxic to many plants and fungi and is implicated as a virulence factor in several major plant diseases. Inhibits the growth of several yeast strains including Rhodotorula pilimanae and Saccharomyces cerevisiae and is also effective against human pathogenic fungi.

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.

Molecular dynamics of the cyclic lipodepsipeptides' action on model membranes: effects of syringopeptin22A, syringomycin E, and syringotoxin studied by EPR technique.

Zsófia Szabó et al.

Biochimica et biophysica acta, 1660(1-2), 118-130 (2004-02-06)

Interaction of pore-forming toxins, syringopeptin22A (SP22A), syringomycin E (SRE) and syringotoxin (ST), with model membranes were investigated. Liposomes were prepared from saturated phospholipids (DPPC or DMPC) or from binary mixtures of DPPC with varying amount of DOPC or cholesterol. The

Actin and amphiphilic polymers influence on channel formation by Syringomycin E in lipid bilayers.

Andrey N Bessonov et al.

European biophysics journal : EBJ, 35(5), 382-392 (2006-02-14)

The bacterial lipodepsipeptide syringomycin E (SRE) added to one (cis-) side of bilayer lipid membrane forms voltage dependent ion channels. It was found that G-actin increased the SRE-induced membrane conductance due to formation of additional SRE-channels only in the case

Effective gating charge of ion channels induced by toxin syringomycin E in lipid bilayers.

Ludmila V Schagina et al.

Bioelectrochemistry (Amsterdam, Netherlands), 60(1-2), 21-27 (2003-08-02)

To elucidate the voltage gating of syringomycin E (SRE) ion channels in lipid bilayers, the effective gating charge q was measured under different conditions. It was shown that q and its sign are dependent on membrane surface charge, dipole potential

IPT1-independent sphingolipid biosynthesis and yeast inhibition by syringomycin E and plant defensin DmAMP1.

Yang Ju Im et al.

FEMS microbiology letters, 223(2), 199-203 (2003-06-28)

Both bacterial cyclic lipodepsipeptide syringomycin E and plant defensin DmAMP1 were shown previously to require expression of the yeast gene IPT1 for fungicidal action against Saccharomyces cerevisiae. IPT1 encodes a sphingolipid biosynthetic pathway glycotransferase that produces the terminal sphingolipid mannosyldiinositolphosphoceramide.
