The Nucleic Acids of T2, T4, and T6 Bacteriophages
The deoxyribonucleic acids of the wild type strains of the T(2), T(4), and T(6) bacteriophages have been shown to contain glucose as an integral part of the molecule; the amount of hexose present in each nucleic acid differs. A study of the acid degradation products of the three nucleic acids has revealed that in each instance glucose is linked to the apurinic acid component. In the case of the...
متن کاملThe structural gene for deoxyribonucleic acid polymerase in bacteriophages T4 and T5.
Genetic studies by Epstein, Edgar, and their colleagues1-3 with conditional lethal (amber and temperature-sensitive) mutants of bacteriophage T4 have led to the construction of a genetic map for this phage, containing approximately 70 different genes of which 20 are believed to function in DNA synthesis. Thus far, only one of these genes has been identified with a specific enzymatic function. W...
متن کاملLysozymes from bacteriophages T3 and T5.
Lysozymes produced in host cells infected with bacteriophages T3 and T5 were found to have the same enzymatic specificity toward the peptidoglycan from Escherichia coli as T7 phage lysozyme, which has been shown to be an N-acetylmuramyl-L-alanine amidase.
متن کاملInfection of Escherichia coli by T2 and T4 bacteriophages as seen in the electron microscope: T4 head morphogenesis.
Bacteriophage T4 capsids seem to be assembled on E. coli protoplasmic membranes. This process seems to involve "lumps" of head protein, which convert to tau particles, which in turn give rise to empty heads. The empty heads leave the bacterial membrane and are then filled with DNA in the central region of the cell. T4 gene 16 and 17 products appear to be necessary for head filling.
متن کاملEffect of prophage W on the propagation of bacteriophages T2 and T4.
Studies have been undertaken to determine whether the temperate phage omega present in Escherichia coli strain W is responsible for the inability of this strain to act as a host for T2 and T4. E. coli WS, cured of phage omega, was sensitive to T2 and T4. Lysogenation of E. coli C and WS with phage omega resulted in loss of ability to plate T2 and T4. However, E. coli K-12 lysogens still served ...
