| - | ==Overview==
| + | |
| - | The crystal structure of the complex formed between the dodecanucleotide d(CGCGAATTCGCG)2 and the drug pentamidine, which is active against the Pneumocystis carinii pathogen in AIDS patients, has been determined to a resolution of 2.1 A and an R-factor of 19.4%. Analysis of the structure has shown the drug to be bound in the 5'-AATT minor groove region of the duplex, with the amidinium groups H-bonded to adenine N3 atoms in an interstrand manner. The drug molecule adopts an extended conformation, and the immediate binding site spans four base pairs. Structural details of the drug-DNA interactions are discussed, and comparison is made with the dodecamer complex of the structurally similar berenil ligand.
