K. Willi et J. Meyer, DNA ANALYSIS OF TEMPERATE BACTERIOPHAGE-AA-PHI-23 ISOLATED FROM ACTINOBACILLUS-ACTINOMYCETEMCOMITANS, MGG. Molecular & general genetics, 258(4), 1998, pp. 323-325
The DNA of the temperate bacteriophage Aa phi 23 isolated from the ora
l bacterium Actinobacillus actinomycetemcomitans was examined structur
ally both in the phage head and in the prophage. The DNA in phage part
icles comprises 44 kb linear molecules with a terminal redundancy of 1
.6 kb, which represent circular permutations. Thus, DNA is packaged in
to phage heads by the headful mechanism. The Aa phi 23 prophage is int
egrated into the host chromosome.
