The morphology of the phage is presented, the buoyant density was determined (1.491 g/ml) and the G + C content of the phage DNA was found to be 44%. The phage genome has a length of 14.8 µm and mol. wt. of 30.7 × 106. Denaturation mapping revealed non-random circular permutation of the phage DNA. The genome exhibits 3.6% terminal redundancy as shown by homoduplex analysis. The existence of concatemeric precursors of phage 5006M DNA is inferred and the results are interpreted in terms of a sequential headful packaging mechanism., UL https://www.microbiologyresearch.org/content/journal/jgv/10.1099/0022-1317-45-2-389
