Abstract

Streptococcus faecalis has been reported to cause food poisoning. Six strains of S. faecalis were tested for Sherman's criteria. These strains were non-hemolytic, DNase+ and Ent+. The enterotoxin was purified on Sephadex G-200 column and maximum activity was observed at 37 C and pH 7.0. Enterotoxin treated with trypsin and papain elicited very poor response to fluid accumulation. The sensitivity of all the strains against different antibiotics was determined. Strain 53 M was treated with acridine orange and ethidium bromide and a total of 44 Amps Strr and 3 Amps Strs mutants were tested for toxin production. Out of these only 4 were toxin negative, amongst which 3 were also DNase negative and 1 showed partial DNase activity.

Characterization of an ATP-driven H+ pump in human placental brush-border membrane vesicles.

The presence of an ATP-driven H+ pump as measured by H+ uptake upon addition of ATP was not demonstrable in human placental brush-border membrane vesicles when used in their native form, owing to their right-side-out orientation. However, the presence of the H+ pump in these membranes became evident when the membrane vesicles were transiently exposed to 1% cholate, with subsequent removal of the detergent to re-form the vesicles. Apparently, cholate pretreatment reoriented the H+ pump from an inward-facing configuration to outward-facing. Consequently, H+ uptake in response to externally added ATP was easily demonstrable in these cholate-pretreated vesicles by using the delta pH indicator Acridine Orange. In addition, bafilomycin A1-sensitive ATPase activity was measurable in cholate-pretreated vesicles, but not in native intact vesicles, indicating reorientation of the H+ pump. The reoriented H+ pump was electrogenic because H+ uptake was stimulated by an inside-negative anion-diffusion potential or when the vesicles were voltage-clamped. ATP supported H+ uptake with an apparent Km of 260 microM. ITP and GTP supported the pump activity partially, whereas CTP and UTP did not. Mg2+ and Mn2+ were the most preferred bivalent cations. Co2+ and Zn2+ showed partial activity, whereas Ca2+ and Ba2+ showed little or no activity. The pump was inhibited by nanomolar concentrations of bafilomycin A1 and micromolar concentrations of N-ethylmaleimide, p-chloromercuribenzenesulphonate, NN-dicyclohexylcarbodi-imide and 7-chloro-4-nitrobenzo-2-oxa-1,3-diazole, but was relatively insensitive to oligomycin, vanadate and NaN3. The inhibition by N-ethylmaleimide was protectable by ATP. It is concluded that human placental brush-border membranes possess an ATP-driven H+ pump and that, on the basis of its characteristics, it belongs to the class of vacuolar (V-type) H+ pumps.

10N-nonyl acridine orange interacts with cardiolipin and allows the quantification of this phospholipid in isolated mitochondria.

The acridine orange derivative, 10N-nonyl acridine orange, is an appropriate marker of the inner mitochondrial membrane in whole cells. We use membrane model systems to demonstrate that 10N-nonyl acridine orange binds to negatively charged phospholipids (cardiolipin, phosphatidylinositol and phosphatidylserine). The stoichiometry has been found to be 2 mol 10N-nonyl acridine orange/mol cardiolipin and 1 mol dye/mol phosphatidylserine or phosphatidylinositol, while, with zwitterionic phospholipids, significant binding could not be detected. The affinity constants were 2 x 10(6) M-1 for cardiolipin-10N-nonyl-acridine-orange association and only 7 x 10(4) M-1 for that of phosphatidylserine and phosphatidylinositol association. The high affinity of the dye for cardiolipin may be explained by two essential interactions; firstly an electrostatic interaction between the quaternary ammonium of nonyl acridine orange and the ionized phosphate residues of cardiolipin and secondly, hydrophobic interactions between adjacent chromophores. A linear relationship was demonstrated between the cardiolipin content of model membranes and the incorporated dye. Consequently, a convenient and rapid method for cardiolipin quantification in membranes was established and applied to the cardiolipin-containing organelle, the mitochondrion.

H+/glycyl-glycine cotransport in eel intestinal brush-border membrane vesicles: studies with the pH-sensitive dye Acridine orange.

Monitoring the fluorescence quenching of the pH-sensitive dye Acridine orange, proton accumulation in the presence of an inside-negative transmembrane potential was measured in eel (Anguilla anguilla) intestinal brush-border membrane vesicles. It was demonstrated that the proton accumulation was specifically increased by the presence of the dipeptide glycyl-glycine in the extravesicular space, showing saturation kinetics at increasing dipeptide concentrations and was specifically inhibited by diethylpyrocarbonate. Data reported suggest the presence of an electrical-potential-dependent H+/glycyl-glycine cotransport system in the eel intestinal brush-border membrane vesicles.
