Structure and Function of RNA Bacteriophages

The crystal structure of bacteriophage GA and a comparison of bacteriophages belonging to the major groups of Escherichia coli leviviruses

“…Bacteriophage GA belongs to group II of the four serological groups of phages, infecting male Escherichia coli bacteria (Fiers, 1979). The native phage particle consists of a single-stranded RNA molecule, packed in an icosahedral protein capsid of T 3 quasi-symmetry (Caspar & Klug, 1962), consisting of 90 chemically identical dimers.…”

Multiple presentation of foreign peptides on the surface of an RNA-free spherical bacteriophage capsid

“…MS2-gp 120. The doublets in some lanes are due to cross-contamination between lanes during loading of the gel, Fiers, 1979) which produces a unique KpnI restriction enzyme cleavage site at position 1378 in the gene sequence (Fig. 2).…”

“…Box 6666, New Haven, Connecticut 06511, U.S.A. extensively characterized genetically and biochemically (Fiers, 1979). The genome consists of a positive-sense ssRNA of 3569 bases, which is encapsidated in a T = 3 surface lattice containing 180 copies of a single coat protein subunit (M r 13-75K).…”

Bacteriophages Folac h, SR, SF: Phages Which Adsorb to Pili Encoded by Plasmids of the S-Complex

“…1 c). If phage Fofac resembles other RNA-containing phages like MS2 (Davis et al, 1961) or Qp (Watanabe et al, 1967) each virion should contain a single molecule of protein A responsible for adsorption to the appropriate pilus (Fiers, 1979). A single particle of phage Folac should adsorb to only one pilus and the above observation cannot be explained without further knowledge, particularly regarding the surface electrical charges involved.…”
