    Notes: Expression of the Escherichia coli kdpABC operon, which is responsible for a high-affinity potassium-uptake system, is regulated in response to a change in the medium osmolarity. In this study, we clarified the structure and function of the kdpABC promoter including its regulatory sequence at the molecular level. The canonical -35 and -10 regions determined for the promoter were not fully functional, i.e. in addition to them, a cis-acting sequence located upstream of the -35 region was essential for full activation of the promoter. This upstream sequence was demonstrated to be the target site for the trans-acting activator, KdpE.

    Notes: The proteins KdpD and KdpE are regulatory factors critically involved in the osmotic regulation of the kdpABC operon that is responsible for a high-affinity transport system in Escherichia coli. In this study, we obtained biochemical evidence supporting the view that the KdpD protein is a sensory protein kinase that exhibits autophosphorylation and KdpE-phosphotransfer characteristics. During the course of such studies we established a procedure for purifying the KdpE protein in large quantities. We also developed a procedure for preparing cytoplasmic membrane enriched with the KdpD protein that exhibits in vitro ability with regard to phosphorylation of KdpE protein.

    Signal transduction between the two regulatory components involved in the regulation of the kdpABC operon in Escherichia coli: Phosphorylation-dependent functioning of the positive regulator, KdpE (1993)

    Notes: The proteins KdpD and KdpE are crucial to the osmotic regulation of the kdpABC operon that is responsible for the high-affinity K+ ion transport system in Escherichia coli. We demonstrated previously that the response regulator, KdpE, is capable of undergoing Phosphorylation mediated by the sensory protein kinase, KdpD. In this study, we obtained biochemical evidence supporting the view that when KdpE is phosphorylated, it takes on an active form that exhibits relatively high affinity for the kdpABC promoter, which in turn results in activation of the kdpABC operon. It was also suggested that the central hydrophobic domain of KdpD, which is conceivably responsible for membrane anchoring of this protein, plays a role in the signalling mechanism underlying KdpE Phosphorylation in response to hyperosmotic stress.

    The effect of actinomycin D on the synthesis of influenza virus-specific RNA (1969)

    Notes: Summary The effect of actinomycin D on the replication of CAM strain of influenza A1 virus was studied in the human conjunctival cell line, clone 1-5C-4. Actinomycin D in a concentration of 0.5 mcg/ml suppressed the virus yield to less than l/1000th of that from the uninhibited culture. When the addition of actinomycin D was delayed, the resistance of the production of virus and viral components to actinomycin D developed progressively in the order of the soluble antigen, hemagglutinin, and the infective virus. The synthesis of virus-specific RNA was demonstrable by the incorporation of tritiated uridine when actinomycin D was added to the culture at 6 hours after infection, but not when it was added at 1 hour after infection. These findings indicated that actinomycin D illhibits influenza virus replication because it inhibits the synthesis of virusspecific RNA and that, however, it does not directly block virus-specific RNA synthesisper se but exerts the inhibitory effect on some event(s) preceding virus-specific RNA synthesis. In FL cells, in which CAM virus undergoes an abortive multiplication cycle, virus-specific RNA was synthesized in the same period after infection and in a similar quantity as in clone 1-5C-4 cells in which complete multiplication occurs.

    Biological functions of monospecific antibodies to envelope glycoproteins of Newcastle disease virus (1984)

    Notes: Summary Monospecific antisera to HN and F glycoproteins of Newcastle disease virus were prepared, and their effects on the biological activities of the virus were investigated. Anti-HN serum inhibited hemagglutinating and neuraminidase activity, as well as hemolysis. Anti-F serum had no effect on hemagglutination or neuraminidase but inhibited hemolysis and virus-induced cell fusion. Anti-HN serum was highly neutralizing, while neutralization by anti-F serum was very inefficient in conventional plaque reduction tests, although both sera were estimated to contain comparable amounts of antibody reacting with the virus as indicated by complement fixation and immunodiffusion tests. The neutralizing activity of anti-F serum was greatly enhanced by the addition of anti-IgG serum or fresh guinea pig serum, whereas that of anti-HN serum was little enhanced. Anti-HN serum incorporated in the agar overlay suppressed the development of plaques to some degree, while anti-F serum had little effect. The combination of anti-HN and anti-F sera resulted in a marked decrease in the number and size of plaques, demonstrating the synergistic effect of the two species of antibody in the containment of the spread of viral infection.

    Protective effect of antibodies to two viral envelope glycoproteins on lethal infection with Newcastle disease virus (1987)

    Notes: Summary The protective effect of humoral immunity against lethal infection of chickens with Newcastle disease virus was studied. Chickens hatched from eggs laid by hens vaccinated with live attenuated Newcastle disease virus vaccine possessed antibody to various components of the virus, and were resistant to a challenge with a virulent strain of Newcastle disease virus which was 100 per cent fatal for the offspring of nonvaccinated hens. Passive administration of antiserum raised against whole virions provided susceptible chickens protection comparable to that seen in the birds with maternal antibody. When administered passively, both anti-HN serum with virus neutralizing activity, and anti-F serum with only marginal virus neutralizing activity significantly prolonged the survival of infected birds but failed to achieve the level of protection as afforded by the anti-whole NDV serum. The protection provided by the simultaneous presence of anti-HN and anti-F serum was significantly greater than that afforded by either alone and comparable to that of anti-whole NDV serum, indicating the complementary effect of anti-HN and anti-F antibodies not only in cell cultures as reported previously (19), but also in a natural host.

    Maturation of measles virus hemagglutinin glycoprotein (1985)

    Notes: Summary The processing of measles virus hemagglutinin glycoprotein (H) in infected cells was studied by pulse-chase method and two-dimensional isoelectric focusing and SDS-polyacrylamide slab gel electrophoresis. H glycoprotein was synthesized initially as polypeptides smaller than H glycoprotein present in the virions. They were then processed into a cohort of polypeptides of larger molecular size and with reduced charge. The change was associated with the expression of H glycoprotein on the cell surface. The removal of sialic acid from carbohydrate chain of H glycoprotein resulted in the shift of isoelectric point to a more basic range. The entire process of maturation of H glycoprotein required approximately 5 hours. Carbohydrate content in H was determined to be approximately 12 per cent by weight. Mannose, galactose, fucose, N-acetylglucosamine, and N-acetylneuraminic acid were the constituent monosaccharides.
