-==Overview==
+==CRYSTAL STRUCTURE OF A DOUBLE-STRANDED DNA CONTAINING THE MAJOR ADDUCT OF THE ANTICANCER DRUG CISPLATIN==
-The success of cisplatin in cancer chemotherapy derives from its ability, to crosslink DNA and alter the structure. Most cisplatin-DNA adducts are, intrastrand d(GpG) and d(ApG) crosslinks, which unwind and bend the duplex, to facilitate the binding of proteins that contain one or more, high-mobility group (HMG) domains. When HMG-domain proteins such as HMG1, IXR (intrastrand-crosslink recognition) protein from yeast, or human, upstream-binding factor (hUBF) bind cisplatin intrastrand crosslinks, they, can be diverted from their natural binding sites on the genome and shield, the adducts from excision repair. These activities sensitize cells to, cisplatin and contribute to its cytotoxic properties. Crystallographic, information about the structure of cisplatin-DNA adducts has been limited, to short single-stranded deoxyoligonucleotides such as, cis-[Pt(NH3)2(d(pGpG))]. Here we describe the X-ray structure at 2.6 A, resolution of a double-stranded DNA dodecamer containing this adduct. Our, information provides, to our knowledge, the first crystallographic look at, a platinated DNA duplex and should help the design of new platinum and, other metal crosslinking antitumour drug candidates. Moreover, the, structure reveals a unique fusion of A- and B-type DNA segments that could, be of more general importance.
