Abstract
The existence of carcinogenic nitrites in food and the natural environment has attracted much attention. Therefore, it is still urgent and necessary to develop nitrite sensors with higher sensitivity and selectivity and expand their applications in daily life to protect human health and environmental safety. Herein, one-dimensional honeycomb-like carbon nanofibers (HCNFs) were synthesized with electrospun technology, and their specific structure enabled controlled growth and highly dispersed bismuth nanoparticles (Bi NPs) on their surface, which endowed the obtained Bi/HCNFs with excellent electrocatalytic activity towards nitrite oxidation. By modifying Bi/HCNFs on the screen-printed electrode, the constructed Bi/HCNFs electrode (Bi/HCNFs-SPE) can be used for nitrite detection in one drop of solution, and exhibits higher sensitivity (1269.9 μA mM-1 cm-2) in a wide range of 0.1~800 μM with a lower detection limit (19 nM). Impressively, the Bi/HCNFs-SPE has been successfully used for nitrite detection in food and environment samples, and the satisfactory properties and recovery indicate its feasibility for further practical applications.

Abstract
Protoglobin from Methanosarcina acetivorans (MaPgb) is a dimeric globin belonging to the same lineage of the globin superfamily as globin-coupled sensors. A putative role in the scavenging of reactive nitrogen and oxygen species has been suggested as a possible adaptation mechanism of the host organism to different gaseous environments in the course of evolution. A combination of optical absorption, electronic circular dichroism (ECD), resonance Raman (rRaman), and electron paramagnetic resonance (EPR) reveal the unusual in vitro reaction of ferric MaPgb with nitrite. In contrast to other globins, a large excess of nitrite did not induce the formation of a nitriglobin form in MaPgb. Surprisingly, the addition of nitrite in mildly acidic pH led to the formation of a stable nitric-oxide ligated ferric form of the protein (MaPgb-NO). Furthermore, the 300-700 nm ECD spectrum of ferric MaPgb is for the first time reported and discussed, showing strong differences in the Soret and Q ellipticity compared to ferric myoglobin, in line with the unusually strongly ruffled haem group of MaPgb and the related quantum-mechanical admixture of the S = 5/2 and S = 3/2 state of its ferric form. The Soret and Q ellipticity change strongly upon formation of MaPgb-NO, revealing a significant effect of the nitric-oxide ligation on the haem group and pocket. The related changes in the asymmetric pyrrole half-ring stretching vibration modes observed in the rRaman spectra give experimental support to earlier theoretical models, in which an important role of the in-plane breathing modes of the haem was predicted for the stabilization of the binding of diatomic gases to MaPgb.

Abstract
Nitric oxide (NO) is an important signaling molecule that is involved in a wide range of physiological and pathological events in biology. Metal coordination chemistry, especially with iron, is at the heart of many biological transformations involving NO. A series of heme proteins, nitric oxide synthases (NOS), soluble guanylate cyclase (sGC), and nitrophorins, are responsible for the biosynthesis, sensing, and transport of NO. Alternatively, NO can be generated from nitrite by heme- and copper-containing nitrite reductases (NIRs). The NO-bearing small molecules such as nitrosothiols and dinitrosyl iron complexes (DNICs) can serve as an alternative vehicle for NO storage and transport. Once NO is formed, the rich reaction chemistry of NO leads to a wide variety of biological activities including reduction of NO by heme or non-heme iron-containing NO reductases and protein post-translational modifications by DNICs. Much of our understanding of the reactivity of metal sites in biology with NO and the mechanisms of these transformations has come from the elucidation of the geometric and electronic structures and chemical reactivity of synthetic model systems, in synergy with biochemical and biophysical studies on the relevant proteins themselves. This review focuses on recent advancements from studies on proteins and model complexes that not only have improved our understanding of the biological roles of NO but also have provided foundations for biomedical research and for bio-inspired catalyst design in energy science.

Abstract
Nitric oxide (NO) is a key signaling molecule in health and disease. While nitrite acts as a reservoir of NO activity, mechanisms for NO release require further understanding. A series of electronically varied β-diketiminatocopper(II) nitrite complexes [CuII](κ2-O2N) react with a range of electronically tuned triarylphosphines PArZ3 that release NO with the formation of O═PArZ3. Second-order rate constants are largest for electron-poor copper(II) nitrite and electron-rich phosphine pairs. Computational analysis reveals a transition-state structure energetically matched with experimentally determined activation barriers. The production of NO follows a pathway that involves nitrite isomerization at CuII from κ2-O2N to κ1-NO2 followed by O-atom transfer (OAT) to form O═PArZ3 and [CuI]-NO that releases NO upon PArZ3 binding at CuI to form [CuI]-PArZ3. These findings illustrate important mechanistic considerations involved in NO formation from nitrite via OAT.

Abstract
![]()
The UV–vis absorption, Raman
imaging, and resonance Raman
(rR) spectroscopy methods were employed to study cyanohemoglobin (HbCN)
adducts inside living functional red blood cells (RBCs). The cyanide
ligands are especially optically sensitive probes of the active site
environment of heme proteins. The rR studies of HbCN and its isotopic
analogues (13CN–, C15N–, and 13C15N–), as well as a careful deconvolution of spectral data, revealed
that the ν(Fe–CN) stretching, δ(Fe–CN) bending,
and ν(C≡N) stretching modes occur at 454, 382, and 2123
cm–1, respectively. Interestingly, while the ν(Fe–CN)
modes exhibit the same frequencies in both the isolated and RBC-enclosed
hemoglobin molecules, small frequency differences are observed in
the δ(Fe–CN) bending modes and the values of their isotopic
shifts. These studies show that even though the overall tilted conformation
of the Fe–C≡N fragment in the isolated HbCN is preserved
in the HbCN enclosed within living cells, there is a small difference
in the degree of distortion of the Fe–C≡N fragment.
The slight changes in the ligand geometry can be reasonably attributed
to the high ordering and tight packing of Hb molecules inside RBCs.

Abstract
A fluorometric and colorimetric dual-mode sensing platform based on graphitic carbon nitrite quantum dots (g-CNQDs) and Fe (II)-bathophenanthroline complex (BPS-Fe2+) was designed to the sensitive detection of nitrite (NO2-) in sausage and water. In this system, the fluorescence of g-CNQDs was quenched by BPS-Fe2+ complex due to the inner filter effect (IFE). When NO2- was present, Fe2+ was oxidized by nitrite to form BPS-Fe3+ complex with BPS, leading to the recovery of the fluorescence from g-CNQDs. Therefore, we constructed a "turn-off-on" fluorescence probe for detection of NO2-. Moreover, with the increase of NO2- concentration, the color of the solution changed from red to colorless, so the UV-vis measurements and on-site visual detection were realized. The method is capable of detecting NO2- in the concentration range of 2.32-34.8 μM with good selectivity and high sensitivity. In addition, the method has the potential to determine NO2- in water samples and sausage samples.

Abstract
The work presents the complementary approach to characterize the formation of various Hb species inside isolated human RBCs exposed to NO, with a focus on the formed Hb-NO adducts. This work presents a complementary approach based on Resonance Raman Spectroscopy (RRS) supported by Blood Gas Analysis, Electron Paramagnetic Resonance Spectroscopy, UV-Vis Absorption Spectroscopy and Mössbauer Spectroscopy to characterize the formation of various Hb species, with a focus on the Hb-NO adducts formed inside isolated human RBCs exposed to NO, under the experimental conditions of low and high levels of oxygen Hb saturation. In the present work, we induced Hb-NO adducts using PAPA-NONOate, a NO-donor with known chemistry and kinetics of NO release, and confirmed the formation of Hb-NO adducts in RBCs incubated with Human Aortic Endothelial Cells (HAECs) stimulated to produce NO. Our results provide a new insight into the formation of Hb-NO adducts after the exposure of RBCs with high oxyHb content to exogenous NO with special attention to the formation of LSHbIIINO in addition to LSHbIINO and metHb (HS/LSHbIIIH2O). We also point out that reliable characterization of Hb-NO adducts requires complementary techniques. Among them, RRS, as a label-free and non-destructive tool, appears to be an important discrimination technique in the studies of Hb-NO adducts inside intact RBCs.

Abstract
Protein-metabolite interactions play important roles in many cellular and physiological processes in biological systems. However, the lack of effective research approaches impedes the understanding of the protein-metabolite interactions. In this study, a novel comprehensive strategy by combining metabolomics platform with native mass spectrometry was developed for investigating the protein-metabolite interactions. Peroxisome proliferator-activated receptors gamma (PPARγ) is a lipid-binding nuclear receptors that plays a key role in regulating fatty-acid oxidation and lipid metabolism, which was selected as the model protein. Seven metabolites including lyso-phosphatidylcholine (LPC) 16:0, LPC18:0, LPC18:1, arachidonic acid, oleic acid, linoleic acid and palmitoleic acid (p < 0.05) were found to have the possible interactions with the PPARγ, these LPCs were discovered as candidate ligands for the first time by using untargeted metabolomics method. Native mass spectrometry based on 15 T Fourier transform ion cyclotron resonance mass spectrometer was employed to directly detect the PPARγ-LPCs complexes to obtain their stoichiometry and kinetic constants. Isothermal titration calorimetry, circular dichroism spectrum and molecular modeling were further utilized to investigate the thermodynamics, conformation and binding mechanism of the interaction between PPARγ and LPCs. It was found that the PPARγ-LPC interaction was an endothermic process, and these LPCs have similar binding constants with stoichiometric number of 1:1. The novel strategy can provide a very useful approach for mapping and identifying unknown protein-metabolite interactions in biological systems.

Abstract
Heme proteins are versatile proteins that are involved in a large number of biological processes. Many spectroscopic methods are used to gain insight into the different mechanistic processes governing heme-protein functions. Since many (intermediate) states of heme proteins are paramagnetic, electron paramagnetic resonance (EPR) methods, such as hyperfine spectroscopy, offer unique tools for these investigations. This perspective gives an overview of the use of state-of-the-art hyperfine spectroscopy in heme research, focusing on the advantages, limits and challenges of the different techniques.

Abstract
Nitrophorins (NPs) catalyze the nitrite dismutation reaction that is unprecedented in ferriheme proteins. Despite progress in studying the reaction mechanism, fundamental issues regarding the correlation of the structural features with the nitrite dismutase activity of NPs remain elusive. On the other hand, it has been shown that the nitrite complexes of NPs are unique among those of the ferriheme proteins since some of their electron paramagnetic resonance (EPR) spectra show significant highly anisotropic low spin (HALS) signals with large gmax values over 3.2. The origin of HALS signals in ferriheme proteins or models is not well understood, especially in cases where axial ligands other than histidine are present. In this study several mutations were introduced in NP4. The related nitrite coordination and dismutation reaction were investigated. As a result, the EPR spectra of the NP-nitrite complexes were found to be tightly correlated with the extent of heme ruffling and protonation state of the proximal His ligand-dictated by an extended H-bonding network at the heme active site. Furthermore, it is established that the two factors are essential in determining the nitrite dismutase activity of NPs. These results may provide a valuable guide for identifying or designing novel heme proteins with similar activity.
