The structure of the domain from simian virus 40 (SV40) large T-antigen, that binds to the SV40 origin of DNA replication (T-ag-OBD131-260) has, been determined by nuclear magnetic resonance spectroscopy. The overall, fold, consisting of a central five-stranded antiparallel beta-sheet, flanked by two alpha-helices on one side and one alpha-helix and one, 3(10)-helix on the other, is a new one. Previous mutational analyses have, identified two elements, termed A (approximately 152-155) and B2, (203-207), as essential for origin-specific recognition. These elements, form two closely juxtaposed loops that define a continuous surface on the, protein. The addition of a duplex oligonucleotide containing the origin, recognition pentanucleotide GAGGC induces chemical shift changes and slows, amide proton exchange in resonances from this region, indicating that this, surface directly contacts the DNA.
