Polysomal localization of R17 bacteriophage-specific protein synthesis.
Synthesis of viral ribonucleic acid (RNA) polymerase, maturation protein, and coat protein in Escherichia coli infected with bacteriophage R17 occurs mainly on polysomes containing four or more ribosomes. The 30S ribosomal subunits through trimer-size polysomes, which are associated with all of the R17-specific proteins and are predominant in the infected cell, synthesize only coat protein. The...
متن کاملEffect of bacteriophage R17 infection on host-directed synthesis of ribosomal ribonucleates.
Studies were performed on the synthesis of ribosomal ribonucleates in cells of Escherichia coli K-12 infected by the ribonucleic acid (RNA) bacteriophage R17. Host-specific RNA was measured in the presence of phage RNA by in vitro hybridization of the purified ribonucleates with E. coli deoxyribonucleic acid. The results showed that, although the overall rate of RNA synthesis was only slightly ...

Bacteriol. 90:928-935. 1965.-When added to Escherichia coli within 2 min after phage R17, 5-fluorouracil (FU), at a concentration of 10(-4)m, completely inhibited the synthesis of infectious ribonucleic acid (RNA) and phage. If the addit...

متن کاملSynthesis of a brain-specific protein (S100 protein) in a homologous cell-free system programmed with cerebral polysomal messenger RNA.
Polyribosomes, carrying nascent polypeptide chains, were prepared from whole brain, cortex, and hindbrain-medullary white matter of young adult rats. In a homologous cell-free system, a brain-specific protein (S100 protein) was identified in the mixture of polypeptides released from the polyribosomes during incubation for 1 hr at 37 degrees . De novo synthesis of the S100 protein was achieved i...
