Sequence analysis of putative pVIII, E3 and fibre regions of porcine adenovirus type 3.
Sequence analysis of a region of the genome of porcine adenovirus type 3 from map unit 79.5 to map unit 92 was performed. Homology studies revealed genes coding for the hexon-associated protein pVIII on the left and for the fibre protein on the right of the sequenced region. By analogy with the genomic organization of other adenoviruses, the 1179 bp sequence between the pVIII and fibre open reading frames, extending from map unit 81.3 to map unit 84.7, was identified as the equivalent of the E3 region of human adenoviruses. The deduced amino acid sequence of one of the three open reading frames of the putative E3 region showed homology with the 13.3K E3 protein of canine adenovirus type 2. The primary structure of the putative fibre protein was similar to that described for human adenovirus types 2 and 5, with a 14 pseudorepeat motif in the shaft region of the fibre. A 742 bp tandem repeat starting in the middle of the fibre gene and extending beyond the termination codon of this gene was observed.
