Texto completoThe hydroxyl radical is widely used as a high-resolution footprinting agent for DNA and RNA. The hydroxyl radical abstracts a hydrogen atom from the sugar- phosphate backbone of a nucleic acid molecule, creating a sugar-based radical that eventually results in a strand break. It was shown previously that replacement of deoxyribose hydrogen atoms with deuterium results in a kinetic isotope effect (KIE) on hydroxyl radical cleavage of DNA. The KIE correlates well with the solvent accessible surface area of a deoxyribose hydrogen atom in DNA. We chose the structurally well-defmed sarcin-ricin loop (SRL) RNA molecule as a model system to extend the deuterium KIE/hydroxyl radical cleavage experiment to RNA. We observed a substantial KIE upon deuteration of the 5'-carbon of the ribose. Values ranged from 1.20 to 1.96, and depended on the position of the residue within the SRL. We found a smaller KIE upon 4'-deuteration. Values ranged from 1.05 to 1.23. Values of 5' and 4' KIEs correlate with the extent of cleavage and with the solvent accessible surface areas of ribose hydrogen atoms ofthe SRL. Gel electrophoresis of cleavage products reveals that the strand break is terminated at the 5' end by multiple chemical species. Upon 3'-radiolabeling a specifically 5'-deuterated SRL RNA molecule, we observed a KIE on the production of a cleavage product having a gel mobility different from that of a phosphate-terminated RNA strand. Reduction with sodium borohydride gave rise to an RNA fragment terminated by a 5'-hydroxyl group. These experiments are consistent with 5' hydrogen abstraction by the hydroxyl radical producing a 5'-aldehyde-terminated RNA strand that retains the nucleotide from which the hydrogen atom was abstracted. This is the first report of such a species. This chemistry has important implications for the interpretation of structural analysis experiments on RNA that rely on primer extension to synthesize eDNA copies of hydroxyl radical cleavage products. The different 5'-terminated products resulting from hydroxyl radical cleavage at a given nucleotide would yield cDNAs of two different lengths, thereby distributing the cleavage intensity over two nucleotides instead ofone and lowering the resolution ofthe experiment.

Texto completoMaster of Science
Home-interior products like cabinetry are often produced with wood composites adhesively bonded with urea-formaldehyde (UF) resin. UF resins are low cost and highly effective, but their chemical nature results in formaldehyde emission from the composite. High emissions are avoided, and the federal government has regulated and steadily reduced allowable emissions since 1985. The industry continuously improved UF technologies to meet regulations, as in 2010 when the most demanding regulations were implemented. At that time, many people were unaware that wood also generates formaldehyde; this occurs at very low levels but heating during composite manufacture causes a temporary burst of natural formaldehyde. Some wood types produce unusually high formaldehyde levels, making regulation compliance more difficult. This situation, and the desire to raise public awareness, created a major industrial goal: determine how much formaldehyde emission originates from the resin and how much originates from the wood. These formaldehyde sources can be distinguished by measuring the carbon isotope ratio, 13C/12C. This ratio changes and varies due to the kinetic isotope effect. Slight differences in 13C and 12C reactivity reveal the source as either petrochemical (synthetic formaldehyde) or plant-based (biogenic formaldehyde). This work demonstrates that achieving the industry goal is entirely feasible, and it provides the analytical foundation. The technical strategy is: 1) establish reference isotope ratios in wood and in UF resin, and 2) from the corresponding wood composite, capture formaldehyde emissions, measure the isotope ratio, and simply calculate the percentage contributions from the reference sources. However, a complication exists. When the reference sources generate formaldehyde, the respective isotope ratios change systematically in a process called isotope fractionation (another term for the kinetic isotope effect). Consequently, this effort developed methods to measure fractionation when cured UF resin and wood separately generate formaldehyde, with greater emphasis on wood. Isotope fractionation in wood revealed multiple fractionation mechanisms. This complexity presents intriguing possibilities for new perspectives on formaldehyde emission from wood and cured UF resin. In summary, this work demonstrated how source contributions to formaldehyde emissions can be determined; it established effective methods required to refine and perfect the approach, and it revealed that isotope fractionation could serve as an entirely novel tool in the materials science of wood composites.
