The location and sequence composition of a consensus element of the nucleotide binding site in both simian virus 40 (SV40) and polyomavirus (PyV) large tumor antigens (T antigens) can be predicted with the assistance of a computer-based pattern-matching system, ARIADNE. The latter was used to optimally align elements of T antigen primary sequence and predicted secondary structure with a "descriptor" for a mononucleotide binding fold. Additional consensus elements of the nucleotide binding site in these two proteins were derived from comparisons of T antigen primary and predicted secondary structures with x-ray structures of the nucleotide binding sites in four otherwise unrelated proteins. Each of these elements was predicted to be encompassed within a 110-residue segment that is highly conserved between the two T antigens residues 418-528 in SV40 T antigen and residues 565-675 in PyV). Results of biochemical and immunologic experiments on the nucleotide binding behavior of these proteins were found to be consistent with these predictions. Taken together, the latter have resulted in a topological model of the ATP binding site in these two oncogene products.
