As shown earlier, phytotoxins produced by Pseudomonas syringae pv. syringae form ion channels of "small" and "large" conductance when incorporated into planar lipid membranes. The multilevel conductance is due to cluster organization of the channels (Kaulin et al., 1998; Gurnev et al., 2002). In this study the kinetic parameters of syringomycin E (SRE) and(More)
We studied effects of toxins produced by a bacterium Pseudomonas syringae pv. syringae on the conductance of bilayer lipid membranes (BLM). The used toxins were as follows: syringopeptin 22A (SP22A), syringomycin E (SPE), syringostatin A (SSA), syringotoxin B (STB), and methylated syringomycin E (CH3-SRE). All toxins demonstrated channel-forming activity.(More)
The effect of filamentous (F) actin on the channel-forming activity of syringomycin E (SRE) in negatively charged and uncharged bilayer lipid membranes (BLM) was studied. F-actin did not affect the membrane conductance in the absence of SRE. No changes in SRE-induced membrane conductance were observed when the above agents were added to the same side of(More)
