Restriction maps of human adenovirus types 2, 5 and 3 for BclI, ClaI, pvul and SphI endonucleases

The sites of cleavage by BclI, ClaI, PvuI and SphI in the DNA from adenovirus (Ad) serotypes 2, 5 and 3 have been located. Certain site coordinates were in accord with nucleotide sequences already published. A small difference in size between the PvuI-E fragments from Ad2 and Ad5 confirmed the existence of a deletion in the N-terminal moiety of Ad5 hexon gene, as previously implied by interserotypic recombinants (Boursnell and Mautner, Virology 112 (1981) 198-209) and more recently by amino acid sequencing (Von Bahr-Lindström et al., Virology 118 (1982) 352-362).
