| heal.abstract | The diastereomeric complexes Lambda- and Delta-[Ru(bpy)(2)(M-bpy-7p)]Cl-2, (bpy = 2,2'-bipyridine, m-bpy-7p = 4-methyl-4'-Arg-Gly-Asn-Ala-His-Glu-Arg-CONH2-2,2'-bipyridine) were synthesized and characterized and their binding properties to the deoxynucleotide duplexes d(5'-CGCGATCGCG-3')(2) and d(5'-GCGCTTAAGCGC-3')(2) were studied by means of H-1 NMR spectroscopy. 7p is part of the recognition loop of the restriction endonuclease MunI, a type II restriction enzyme from Mycoplasma unidentified which recognizes the palindromic hexanucleotide sequence C/AATTG and cleaves it as indicated by the slash. The A-isomer binds to the terminal CG/GC major groove of d(CGCGATCGCG)(2) decanucleotide, whereas the A-isomer approaches the GCT/CGA sequence. On the other hand, weak binding of the Delta-isomer to the end of d(GCGCTTAAGCGC)(2) into two different orientations is observed. In the case of the A-isomer, the bpy ligand(s) are located into the major groove of the central TT/AA sequence. The role of appended peptide sequences in sequence selectivity binding to DNA is being addressed. (C) 2004 Elsevier Inc. All rights reserved. | en |
