We have applied Fe-57 nuclear resonance vibrational spectroscopy (NRVS) to identify protein-bound dinitrosyl iron complexes. Intense NRVS peaks due to vibrations of the N-Fe-N unit can be observed between 500 and 700 cm(-1) and are diagnostic indicators of the type of iron dinitrosyl species present. NRVS spectra for four iron dinitrosyl model compounds are presented and used as benchmarks for the identification of species formed in the reaction of Pyrococcus furiosus ferredoxin D14C with nitric oxide.

High-Frequency Fe-H and Fe-H2 Modes in a trans-Fe(η2-H2)(H) Complex: A Speed Record for Nuclear Resonance Vibrational Spectroscopy

Ming-Hsi Chiang, Vladimir Pelmenschikov, Leland B. Gee, Yu-Chiao Liu, Chang-Chih Hsieh, Hongxin Wang, Yoshitaka Yoda, Hiroaki Matsuura, Lei Li, Stephen P. Cramer

Summary: Nuclear resonance vibrational spectroscopy (NRVS) and density functional theory (DFT) are complementary tools for studying the vibrational structures of molecular systems. By applying NRVS and DFT to study the trans-[Fe-57(eta(2)-H-2)(H)(dppe)(2)][BPh4] complex, it has been shown that NRVS can quantitatively analyze sample composition.

Alkyl Complexes of Iron(IV) Triphenylcorrole

Kenneth P. Caulfield, Zachary J. Tonzetich

Summary: This study investigates the reaction of iron corrole complex with alkyl halides, finding that the products have resistance to beta-H elimination and exhibit stability. The thermal decomposition of the products also reveals the formation of ethylene and acetaldehyde, as well as ethyl phenyl thioether when radical traps are present. The reaction of iron with NO results in the formation of iron nitrosyl species. Kinetic analysis of the alkylation reaction suggests that it follows either an S(N)2 type pathway or an outer-sphere electron transfer.

Summary: Electron bifurcation allows energetically unfavorable biochemical reactions to occur. This study reports a new bifurcating flavoenzyme structure that couples hydrogen oxidation with NAD reduction through electron transfer. By elucidating its structure and function, we gain a deeper understanding of the electron transfer pathways in hydrogenases.

Synthesis and Reactivity of Iron(II) Acetylide Complexes Relevant to Alkyne Dimerization

Vance Thompson, Ana L. Narro, Hadi D. Arman, Zachary J. Tonzetich

Summary: Iron(II) phenylacetylide complexes of pyrrole-based pincer ligands were synthesized and characterized. In solution, the acetylide compounds of both ligands exist as square planar, intermediate-spin species. Interconversion between iron enynyl species was observed during catalytic alkyne dimerization.

Adaptations to high pressure of Nautilia sp. strain PV-1, a piezophilic Campylobacterium (aka Epsilonproteobacterium) isolated from a deep-sea hydrothermal vent

Francesco Smedile, Dionysis Foustoukos, Sushmita Patwardhan, Kelli Mullane, Ian Schlegel, Michael W. Adams, Gerrit J. Schut, Donato Giovannelli, Costantino Vetriani

Summary: Physiological and gene expression studies of deep-sea bacteria under pressure conditions similar to their natural habitat are important for understanding their growth kinetics and metabolic adaptations. This study focused on Campylobacterium Nautilia sp. strain PV-1, a piezophilic bacterium that displays unique protein expression patterns in response to different hydrostatic pressure regimes. The findings suggest that pressure adaptation extends to enzymes involved in central metabolic pathways.

Tracking energy scale variations from scan to scan in nuclear resonant vibrational spectroscopy: In situ correction using zero-energy position drifts ΔEi rather than making in situ calibration measurements

Jessie Wang, Yoshitaka Yoda, Hongxin Wang

Summary: Nuclear resonant vibrational spectroscopy (NRVS) is an excellent modern vibrational spectroscopy method for revealing site-specific information inside complex molecules such as enzymes. This study evaluates the trends and mechanisms of zero-energy drifts (Delta E-i) in NRVS spectra and explores their correlation with energy scales (alpha(i)) between scans. Through detailed analysis, a new stepwise procedure for practical energy calibration is established, which uses Delta E-i values to correct for scan-dependent energy variations instead of conducting additional in situ calibration measurements. It is also proven that an additional instrument-fixed scaling constant (a(0)) exists to convert the calibrated energy axis (E') to the real energy axis (E-real). The calibrated real energy axis (E-real) has a preliminary error bar of +/- 0.1%, which is 4-8 times better than the current practical energy calibration procedure.

Mixed heavy metal stress induces global iron starvation response

Summary: Multiple heavy metal contamination is a common global problem that can disrupt microbial biogeochemical cycling. However, there is a lack of studies on the effects of combinations of heavy metals on bacteria. In this study, we assessed the impact of eight metal contaminants on cell processes using a multiomics approach. The combination of metals had unexpected effects on cell physiology, including a disruption of iron homeostasis and decreased activity of important enzymes. This research highlights the need for multi-metal studies to understand the impacts of complex contaminants on microbial systems.

Mixed nitrate and metal contamination influences operational speciation of toxic and essential elements

Summary: Environmental contamination affects microbial communities by limiting diversity and total metabolic activity. The study investigates metal contamination in sediment and finds that the operational speciation of certain elements changes due to contamination. Furthermore, the availability of essential elements also changes. The decreased operational speciation of phosphorus in contaminated sediment may increase the dependence of microbial communities on other phosphorus sources.
