 Title    Isolation and Characterization of a Potassium Specific Ionophore from Streptococcus fuecalis  
 Abstract    The synthesis of a potassium and rubidium specific ionophore by S treptococcu s faecalis has been proved, using bilayer measurements. The characteristics of this substance agree with the ones, published for free mobile carriers, such as valinomycin and the macrotetrolides.

 Title    Variability of Conductivity Changes in Black Phosphatidylserine Membranes Induced by Proteins from Erythrocyte Membranes  
 Abstract    The electrical conductivity of black phosphatidylserine membranes, in solutions of 100 mM NaCl, 10 m M sodium phosphate (pH 7.1), is strongly increased by the intrinsic proteins ("strongly bound" protein fraction) from human erythrocyte membranes. The magnitude of the conductivity increase is highly dependent on the maximum pH-value pH* used during the preparation of the protein (8.0 pH* 11.8). For each pH*, membrane conductivity kf and protein concentration c are linked by the equation Af=Zc-cs, k and s being functions only of pH*. The value of s varies between 1.0 (pH* 8) and 4.0 (pH* 10). It is assumed that the protein-induced conducting sites, at least for protein pretreatment at pH* 5^ 10, are assembled from four protein subunits. The in­ corporation of the subunits into the lipid bilayer is supposed to occur either as the final tetramer (pH* 8) or as monomers (pH* 10) and possibly dimers (pH* around 9).

 Title    A Cell for Simultaneous Measurements of Optical and Electrical Properties of Black Lipid Membranes  
 Abstract    A universal cell was constructed, which allows measurements of the resistance (d. c.), capacity, optical reflectivity, and spectral absorption of blade lipid films simultaneously. These measurements reflect different properties of the films, supplementary to each other. The purpose is to eliminate differences of experimental conditions especially in recombination experiments with proteins. The cell is totally symmetric, can be completely disassembled, and the parts are exchangeable. It allows application of several methods for film production, and is held together simply by mechanical pressure, without need of any sealing agent. The inner parts are exclusively of glass and teflon. The fluid volume of the cell is 7 —15 ml and the better than 1014 Ohms.
