Structure and gene organization in the transformed Hind III-G fragment of Ad12.
The nucleotide sequence of the transforming Hind III-G fragment of Ad12 DNA which encompasses the left 6.8% of the genome has been determined. The fragment was 2320 nucleotides long, and contained a GC cluster at positions 126-155 and a region extremely rich in AT at positions 1098-1142 (number from the leftmost end). Possible coding regions for the two transforming gene products were assigned. The predicted coding region for T antigen g is positions 502-1069 and positions 1144-1373, which are joined by splicing (266 amino acid residues, 30 kd), and that for T antigen f is positions 1845-2126 (94 amino acid residues, 10 kd). The sequence of the Hind III-G fragment was compared with that of the transforming DNA fragment of Ad5 which encompasses the left 8.0% of the genome (2809 nucleotides). There are several discrete regions with significant sequence homology. The comparison suggests that the regions in the left two thirds of the Ad5 and Ad12 transforming DNA fragments (map units 0-4.7% in Ad5 and 0-4.4% in Ad12) bear some resemblance in their gene organizations, and code for proteins containing structurally homologous regions.
