title: [Sequencing of right terminal fragment of canine adenovirus type 1 vaccine strain DNA].
abstract: Current studies show that adenoviruses are more advantageous as expression vectors than other viruses. Canine adenovirus type 1 (CAV-1) vaccine strain, CLL (cannaught laboratory limited), as vectors will play more important role for the prophylaxis of zoonosis than human adenoviruses. Studies on molecular biology of CAV-1 or CLL are necessary for construction of vectors of CLL. In this paper, the right terminal of CLL DNA cleaved by Hind II was sequenced. Authors found that it contained a 238 bp inverted terminal repeats (ITR). There are three copies of 40 bp short repeat sequences in the ITR. According to the DNA structural model of human adenovirus type 2, the 40 bp short repeats are the sites that are combined with nuclear factor 1 (NF-1) that is an initiation factor of DNA replication of virus, so they are essential structure of CLL DNA.
