Abstract

Initiation of adenovirus DNA replication in vitro occurs on a linearized plasmid DNA containing 3,327 base pairs of the adenovirus terminal sequence. Various deletions have been constructed in the plasmid DNA and their template activities examined. Deletions from an internal restriction enzyme cleavage site that retain only 20 base pairs or more of the adenovirus terminal sequence support initiation and limited chain elongation, whereas deletions that leave 14 base pairs or less of the terminal sequence do not. On the other hand, all deletions extending from the very terminus of the adenovirus DNA destroy the template activity. The terminal 20 base pairs of adenovirus DNA contain a sequence A-T-A-A-T-A-T-A-C-C, which is perfectly conserved in the DNAs from different serotypes of human adenovirus. Base changes within the conserved sequence greatly reduce the template activity. These results suggest that the terminal 20 base pairs constitute a functional origin for the initiation of adenovirus DNA replication in vitro.
