Addition Radicals Formed by Hydroxyl Radical Bombardment of Uracil
Science, 1966Direct addition of O—H radicals at room temperature to the carbon No. 5 of the uracil ring has been proved by measurement of the proton hyperfine structure in the electron spin resonance of the resulting uracil + O—H radicals. Upon addition of the OH, the H originally bound to carbon No. 5 shifts to No. 6, thus forming a methylene group at carbon No. 6,

DNA Footprinting with the Hydroxyl Radical
Free Radical Research Communications, 1991The Fenton reaction of iron(II) EDTA with hydrogen peroxide, performed in the presence of ascorbate ion, has proven to be useful as a probe of structure in DNA systems. Two aspects of this chemistry are discussed: the identity of the active DNA cleaving agent produced by this reagent, and the application of the Fenton reaction to the determination of ...

The Hydroxyl Radical in Flames
Nature, 1928THE evidence in favour of the view that the hydroxyl radical is present in flames has been summarised recently by Bonhoeffer and Haber (Z. Phys. Chem., 137, 263; 1928). There is no doubt that this radical is the emitter of the 3064 A. band, present in the spectra of hydrogen flames, and Hulthen and Zumstein, and Bonhoeffer have shown that this band ...

Abstract Hydroxyl radicals have now been used for more than 15years to probe the structure of various macromolecules. They have also been widely used to footprint DNA-protein and RNA-protein complexes (1, 2). Hydroxyl radicals are w1y small, comparable in size to a water molecule, are most commonly generated from FeEDTA in solution by
