Pseudomonas toxin binds triton X-114 at low pH.


Pseudomonas toxin was found to bind Triton X-114 at pH values below pH 5.0, whereas much less binding was observed at higher pH values. The toxin bound Triton X-114 at a higher pH value in the presence of 0.14 M-NaCl, -KCl or -NaNO3 than at low salt concentrations. The results suggest that low pH in an intracellular compartment facilitates the transport of… (More)
