sequential protein synthesis following vaccinia virus infection.inhibition of hela cell protein synthesis and the sequential synthesis of viral proteins were followed by pulse-labeling infected cells with (14)c-phenylalanine. proteins were resolved by polyacrylamide gel electrophoresis. the viral origin of native proteins was confirmed by immunodiffusion. the inhibition of host protein synthesis and the synthesis of early viral proteins occur 1 to 3 hr after infection. this early sequence of events also occurs in the presence of 5-fluorodeoxyuridine, an inhi ...19684235537
synthesis and intracellular localization of vaccinia virus deoxyribonucleic acid-dependent ribonucleic acid polymerase.the time course of vaccinia deoxyribonucleic acid (dna)-dependent ribonucleic acid (rna) polymerase synthesis and its intracellular localization were studied with virus-infected hela cells. viral rna polymerase activity could be meassured shortly after viral infection in the cytoplasmic fraction of infected cells in vitro. however, unless the cells were broken in the presence of the nonionic detergent triton-x-100, no significant synthesis of new rna polymerase was detected during the viral grow ...19684235691

sequential formation of vaccinia virus proteins and viral deoxyribonucleic acid replication.in vaccinia virus-infected cell cultures, cellular protein synthesis was inhibited 50% at 2 hr postinfection (pi) and 80 to 90% by 4 hr pi. input virus was responsible for this inhibition. five early proteins, coded for by the viral genome, could be detected at 2 to 3 hr pi. normally, their synthesis did not continue beyond 6 hr pi, at which time synthesis of a different set of proteins began. when dna replication was blocked, synthesis of these early proteins continued until 9 to 12 hr pi. the ...19674248263
vaccinia virus structural polypeptide derived from a high-molecular-weight precursor: formation and integration into virus particles.polypeptide 4a, a major vaccinia structural polypeptide which was previously shown to form from a high-molecular-weight precursor is made after the period of viral deoxyribonucleic acid (dna) synthesis. pulse-chase experiments demonstrated that a period of 1 to 2 hr is required for a 50% conversion of precursor to product. the rates of incorporation of polypeptides into virus particles were examined. the kinetics of incorporation of labeled 4a and other major structural polypeptides into virus p ...19704250367

binding of deoxyribonucleic acid-dependent deoxyribonucleic acid polymerase to poxvirus.poxvirus has a deoxyribonucleic acid polymerase activity that remains associated with the virus despite repeated centrifugation through sucrose gradients. highly purified poxvirus preparation can adsorb deoxyribonucleic acid polymerase from cytoplasmic extracts of cells containing such an activity. these results indicate that caution must be used in assuming that an enzyme associated with a purified virus is necessarily an integral part of the virion.19724258045

hemadsorption-negative plaque test: new assay for rubella virus revealing a unique interference.a simple and rapid plaque procedure has been developed for detecting and accurately assaying rubella virus in a noncytopathic virus-cell relationship. plaque-formation is based on the development, in individual cells infected with rubella virus, of a unique type of intrinsic interference to infection with newcastle disease virus. rubella virus-infected cells challenged with newcastle disease virus and tested for hemadsorption 15 hours later stand out as hemadsorption-negative areas. individual l ...19654283964
