Voltage-dependent Block of Anthrax Toxin Channels in Planar Phospholipid Bilayer Membranes by Symmetric Tetraalkylammonium Ions
Previous studies have shown that symmetric tetraalkylammonium ions affect, in a voltage-dependent manner, the conductance of membranes containing many channels formed by the PAn5 fragment o f anthrax toxin. In this paper we analyze this phenomenon at the single-channel level for tetrabutylammonium ion (Bu4N+). We find that Bu4N + induces a flickery block of the PA65 channel when present on eith...
متن کاملReduction of metal ions by boranephosphonate DNA.
Oligodeoxyribonucleotides bearing boranephosphonate linkages (bpDNA) were shown to reduce a number of metal ions and form nanoparticles through a novel reaction pathway that leads to phosphate diesters or phosphate triesters in water or alcohols respectively. The synthetic utility of this reaction was further demonstrated through the synthesis of oligodeoxyribonucleotides containing phosphate t...
متن کاملRadiation of water waves by a heaving submerged horizontal disc
A thin rigid plate is submerged beneath the free surface of deep water. The plate performs small-amplitude oscillations. The problem of calculating the radiated waves can be reduced to solving a hypersingular boundary integral equation. In the special case of a horizontal circular plate, this equation can be reduced further to onedimensional Fredholm integral equations of the second kind. If th...
متن کاملHeaving Point Internal Mass
A design study has been made of a wave energy converter in the form of a heaving buoy reacting against an internal moving mass. Phase control has been obtained by modulating the stiffness of the spring governing the moving mass. Promising results, agreeing closely with linear theory, have been obtained with two shapes of buoy. Mean annual captures of the order of 2OOW/tonne in a typical South U...
متن کاملDiffusion limitation in the block by symmetric tetraalkylammonium ions of anthrax toxin channels in planar phospholipid bilayer membranes
Current flow through the channel formed in planar phospholipid bilayer membranes by the PA65 fragment of anthrax toxin is blocked, in a voltage-dependent manner, by tetraalkylammonium ions (at micromolar concentrations), which bind to a blocking site within the channel lumen. We have presented evidence that diffusion plays a significant role in the kinetics of blocking by tetrabutylammonium ion...
