Bacteria that oxidize methane to methanol are central to mitigating emissions of methane, a
potent greenhouse gas. The nature of the copper active site in the primary metabolic …

The electronic structures of the native Mn4O x Ca cluster and the biosynthetically substituted
Mn4O x Sr cluster of the oxygen evolving complex (OEC) of photosystem II (PSII) core …

The heart of the oxygen-evolving complex (OEC) of photosystem II is a Mn4O x Ca cluster
that cycles through five different oxidation states (S0 to S4) during the light-driven water …

In nature, methane is oxidized to methanol by two enzymes, the iron-dependent soluble
methane monooxygenase (sMMO) and the copper-dependent particulate MMO (pMMO) …

The electronic structure and ground spin states, S, observed for mixed-valent iron–sulfur
dimers (FeII-FeIII) are typically determined by the Heisenberg exchange interaction, J, that …

The active site of the 57Fe-enriched [FeFe]-hydrogenase (ie, the “H-cluster”) from
Desulfovibrio desulfuricans has been examined using advanced pulse EPR methods at X …

Proton Dynamic Nuclear Polarization (DNP) experiments were conducted on a 3.4 T
homebuilt hybrid pulsed-EPR-NMR spectrometer, on static samples containing 10 mM or 40 …

In this report, we investigate the physical and chemical properties of monocopper Cu (I)
superoxo and Cu (II) peroxo and hydroperoxo complexes. These are prepared by …

Purpose Tissue oxygen (O2) levels are among the most important and most quantifiable
stimuli to which cells and tissues respond through inducible signaling pathways. Tumor O2 …

The set-up of a new microwave bridge for a 95GHz pulse EPR spectrometer is described.
The virtues of the bridge are its simple and flexible design and its relatively high output …
