title: Bacteriophages of Halobacterium halobium: virion DNAs and proteins.
abstract: The DNAs from bacteriophages Hh-1 and Hh-3 that infect Halobacterium halobium were characterized. Both phages contain linear double-stranded DNA and show no relatedness based on restriction endonuclease fragment patterns. Hh-1 DNA has 67.05% guanine plus cytosine (G+C) and a molecular weight of 24.6 X 10(6), whereas Hh-3 DNA has 62.15% G+C and a molecular weight of 19.4 X 10(6). Polyacrylamide gel electrophoresis indicated that the major proteins of the two phages are of different molecular weights.
