Mono- and Dinuclear Nonheme Iron Model Complexes: O-O Bond Activation, Structural Characterization and Reactivity Study
… and reactivities of mono- and dinuclear nonheme iron model complexes were investigated. In Chapters 2 and 3, O-O bond activation of H2O2 by the dinuclear complexes [(FeIII2(μ-O)(μ-OH)L2]3+ (1A) and [(FeIII2(μ-OH)2L2]4+ (2A), L = tris(3,5-di-methyl-4-methoxypyridyl-2-methyl)amine, to form …

The effect of two reheating methods and storage on the development of warmed-over flavor in precooked chicken parts
… storage did not have a significant effect on the nonheme iron content of breasts or legs. The effects of heating temperature were inconsistent for the legs and breasts which was attributed to the different initial iron content of the legs, and the release of nonheme iron during the initial …

Structural and functional investigations of mechanisms of iron-utilizing enzymes
Biological systems use iron as a key cofactor to catalyze a variety of difficult chemical transformations, particularly as reservoirs from which to initiate enzymatic radical chemistry. Here, I discuss efforts to study the allosteric mechanisms of an essential human iron and free radical utilizing …

Predicting learning success from patterns of pre-training magnetic resonance images
… (ASL). We then discovered that (patterns of) nonheme iron (not heme) is the underlying factor driving learning prediction. This discovery of the relationship between iron concentrations and learning ability in healthy young adults could not only guide the development of potential neuromarkers …

Mechanisms of Enzyme Neofunctionalization in Plant Specialized Metabolism
… metabolism by examining two enzyme families: nonheme iron(II)- and 2-oxoglutarate-dependent halogenase and BAHD acyltransferase. First, we describe the genomic- and biochemical-basis for gene duplication and neofunctionalization of flavonol synthase (FLS) that led to the unique emergence of …

Investigations of metalloenzymes involved in bacterial natural product biosynthesis
… (SAM) superfamily, with its required iron-sulfur cluster and cobalamin (B12) cofactors. The methyl transfer reaction catalyzed by Fom3 was then investigated in vitro using a combination of isotope labeling, enzymatic synthesis, liquid chromatography-mass spectrometry, and nuclear …
