Comparative receptor modelling study of TSP, PM2 and PM2−10 in Ho Chi Minh City

Atmospheric Environment, 2001
Abstract Elemental compositions were measured for TSP (total suspended particulate matter), PM2−10 and PM2 (particulate matter with aerodynamic diameters from 2 to 10 μm and less than 2 μm, respectively) in Ho Chi Minh City. Concentrations of 23 elements and particulate mass (PM) were used for receptor modelling to identify and quantify aerosol ...

Lipid and Protein Arrangement in Bacteriophage PM2

Nature New Biology, 1971
X-ray structure analysis shows that the lipid of bacteriophage PM2 is organized in a bilayer. These results provide a basis for interpreting electron micrographs of the virus in molecular terms.

Catenanes of closed circular intracellular PM2 phage DNA

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1974
Abstract The closed circular intracellular DNA isolated from Pseudomonas BAL 31 20 min after infection with PM2 phage contains 5% catenated forms. The existence of catenated dimers is demonstrated by isolation of this species as a middle band in a propidium iodide—CsCl gradient, by electron microscopy and by sedimentation studies.

Membrane-localized replication of bacteriophage PM2

Virology, 1978
Abstract The DNA of bacteriophage PM2 was labeled in vivo to maximum specific activity with [ 3 H]thymidine. Labeled virus was purified and then used to infect the unlabeled host Pseudomonas BAL-31. As revealed by electron microscope autoradiography, the infecting DNA was not distributed evenly inside the cell but remained localized at the ...

Interaction between bacteriophage PM2 protein IV and DNA

Journal of Molecular Biology, 1979
Abstract The interaction between DNA and the structural protein IV of bacteriophage PM2 was studied by co-sedimentation, filter binding and electron microscopy. The co-sedimentation data and the sigmoid-shaped filter binding curve were interpreted in terms of co-operative binding. At a given DNA/protein input ratio, some DNA molecules were associated

Relating cistrons and functions in bacteriophage PM2

Virology, 1985
An approach to correlate functions with cistrons in bacteriophage PM2 is presented. Two of the temperature-sensitive mutants obtained differed from the wild type in heat sensitivity and four differed in host range. Comparison of the electrophoretic patterns of DNA from cells infected at the restrictive temperature with those obtained in wildtype ...

Meteorological and Emission Influences on PM2.5 Concentration in South Korea during the Seasonal Management: A Case of December 2019 to March 2020

, 2020
The nation-wide PM2 5 concentration from December 2019 to March 2020 (2019 Winter) in South Korea was observed as low as 24 mu g/m(3), showing the lowest seasonal mean PM2 5 concentrations for the last five years Consequently, the PM2 5 concentration ...

DNA-dependent RNA Polymerase associated with Bacteriophage PM2

Nature New Biology, 1972
A DNA-dependent RNA polymerase is associated with purified preparations of bacteriophage PM2. The template is DNA, as suggested by the reduction in polymerase activity on treatment of disrupted virus particles with DNAase and by the absence of detectable amounts of RNA in the virus.

Control of membrane morphogenesis in bacteriophage PM2

Journal of Supramolecular Structure, 1976
AbstractThe regulation of membrane formation in bacteriophage PM2 serves as a simple model for changes in membrane structure in eukaryotic cells. Prior to Pseudomonas host lysis, wild‐type virions mature to an icosahedral morphology at the inner face of the cytoplasmic membrane.
