The Pseudomonas syringae pv. syringae phytotoxins syringomycin-E and syringopeptins 22-A and 25-A reversibly and noncompetitively inhibit purified H+-ATPase solubilized from plasma membrane of maize roots. Moreover, they increase the passive permeability to protons in phosphatidylcholine/phosphatidylethanolamine liposomes. Both effects are more pronounced with syringopeptins than with syringomycin-E. Activity on phospholipid bilayers is detectable at phytotoxin concentrations not affecting H+-ATPase activity.
