Oxygen Activating Enzymes

Piperonyl butoxide is an inhibitor of the mixed-function oxidase system. [Pg.82]

Thus, in this heme paradigm, the porphyrin plays an active role in accessing the high-valent oxidation state required for the substrate oxidations. Many of the proposed mechanisms for the nonheme iron oxygen activating enzymes follow this mechanistic model. An important question is how analogous chemical reactions can be carried out in the absence of a porphyrin ligands alternatively, what... [Pg.270]

My research program on nonheme iron oxygen activating enzymes and models thereof has been generously supported by the National Institutes of Health (GM-33162, GM-38767) and the National Science Foundation (DMB-9405723 and... [Pg.312]

The characteristics of intermediates MMOH-Q and RNR R2-X continue to converge. The radiolytic reduction of MMOH-Q affords an Fe(III)/Fe(I V) form designated Qx, which has Mossbauer properties similar to RNR R2-X [25]. This work and the recent EXAFS characterization of MMOH-Q and RNR R2-X [26-28], revealing that the two intermediates have very similar core structures, provide strong support that the 02 reaction chemistry in these two enzymes is analogous. This notion very likely extends to the other diiron oxygen activating enzymes. [Pg.590]

Enzymes have evolved to couple efficiently the reduction of dioxygen to the oxidation of biological compounds. Difficult C-H abstraction and O-atom insertion reactions are catalyzed by oxygen-activating enzymes under mild conditions and with high specificity. [Pg.1393]
