Abstract
The 15-mer oligodeoxynucleotide GGTTGGTGTGGTTGG is a potent inhibitor of thrombin and it forms a stable, highly compact structure in solution. Deletions and substitutions by abasic residues, 2′-deoxyinosine, 7-deaza-2′-deoxyguanosine and 8-methyl-2′-deoxyguanosine show that the structural features of the oligodeoxynucleotide are important for its biological activity.
