摘要：

Oxochromium(v) centres initiate DNA cleavage through a chromium(v)phosphate diester intermediate by hydrogen abstraction from the C-1' position of the ribose sugar, leading to the formation of 5-methylene-2-furanone, 3'-phosphate terminus and DNA bases; by contrast a plasmid DNA (pUC19) is only nicked.
