Abstract
OBJECTIVES This study was designed to investigate metabolic biomarker changes and related metabolic pathways of Butylphthalide (NBP) on cerebral ischemia/reperfusion. METHODS In this study, a mouse cerebral ischemia/reperfusion (I/R) model was prepared using the middle cerebral artery occlusion method, and neurobehavioral score and 2, 3, 5-triphenyltetrazolium chloride (TTC) staining experiments were used to confirm the obvious NBP anti-cerebral ischemia effect. The protective effect of NBP in the mouse cerebral I/R model and its metabolic pathway and mechanism were investigated using mouse blood samples. RESULTS The metabolic profiles of mice in the I/R+NBP, I/R, and sham groups were significantly different. Under the condition that I/R vs. sham was downregulated and I/R + NBP vs. I/R was upregulated, 88 differential metabolites, including estradiol, ubiquinone-2, 2-oxoarginine, and L-histidine trimethylbetaine, were screened and identified. The related metabolic pathways involved arginine and proline metabolism, oxidative phosphorylation, ubiquitin and other terpenoid-quinone biosynthesis, and estrogen signaling. CONCLUSIONS Metabolomics was used to elucidate the NBP mechanism in cerebral ischemia treatment in mice, revealing synergistic NBP pharmacological characteristics with multiple targets.

Abstract
Detection of cellular metabolites that are disease biomarkers is important for human healthcare monitoring and assessing prognosis and therapeutic response. Accurate and rapid detection of microbial metabolites and pathway intermediates is also crucial for the process optimization required for development of bioconversion methods using metabolically engineered cells. Various redox enzymes can generate electrons that can be employed in enzyme-based biosensors and in the detection of cellular metabolites. These reactions can directly transform target compounds into various readout signals. By incorporating engineered enzymes into enzymatic cascades, the readout signals can be improved in terms of accuracy and sensitivity. This review critically discusses selected redox enzymatic and chemoenzymatic cascades currently employed for detection of human- and microbe-related cellular metabolites including, amino acids, d-glucose, inorganic ions (pyrophosphate, phosphate, and sulfate), nitro- and halogenated phenols, NAD(P)H, fatty acids, fatty aldehyde, alkane, short chain acids, and cellular metabolites.

Abstract
Histidine (His) is an essential amino acid that plays an important biological role and associated with various pathological conditions. A simple and reliable method for the determination of endogenous histidine in human saliva was optimized and validated. The analyte was separated from the saliva matrix by cation exchange chromatography and detected fluorimetrically (λex/λem = 360/440 nm) after online, specific post-column derivatization (PCD) reaction with o-phthalaldehyde. The chemical and instrumental variables of the post-column reaction were optimized using Box-Behnken experimental design to achieve maximum sensitivity. Method validation was carried out employing the total-error concept. Histidine could be analyzed reliably in the range of 0.5-5.0 μΜ, with an LOD (S/N = 3) of 50 nM. Monte Carlo simulations and capability analysis were used to investigate the ruggedness of the PCD reaction. The sampling strategy, sample preparation and stability were also investigated. Seventeen saliva samples were successfully analyzed with histidine levels being in the range of 2.7-19.5 μΜ.

Abstract
Specific flavoenzyme oxidases catalyze oxidative decarboxylation in addition to their classical oxidation reactions in the same active sites. The mechanisms underlying oxidative decarboxylation by these enzymes and how they control their two activities are not clearly known. This article reviews the current state of knowledge of four enzymes from the l-amino acid oxidase and l-hydroxy acid oxidase families, including l-tryptophan 2-monooxygenase, l-phenylalanine 2-oxidase and l-lysine oxidase/monooxygenase and lactate monooxygenase which catalyze substrate oxidation and oxidative decarboxylation. Apart from specific interactions to allow substrate oxidation by the flavin cofactor, specific binding of oxidized product in the active sites appears to be important for enabling subsequent decarboxylation by these enzymes. Based on recent findings of l-lysine oxidase/monooxygenase, we propose that nucleophilic attack of H2O2 on the imino acid product is the mechanism enabling oxidative decarboxylation.

Abstract
Enzymatic amino acid assays are important in physiological research and clinical diagnostics because abnormal amino acid concentrations in biofluids are associated with various diseases. L-histidine decarboxylase from Photobacterium phosphoreum (PpHDC) is a pyridoxal 5'-phosphate-dependent enzyme and a candidate for use in an L-histidine quantitation assay. Previous cysteine substitution experiments demonstrated that the PpHDC C57S mutant displayed improved long-term storage stability and thermostability when compared with those of the wild-type enzyme. In this study, combinational mutation experiments of single cysteine substitution mutants of PpHDC were performed, revealing that the PpHDC C57S/C101V/C282V mutant possessed the highest thermostability. The stabilizing mechanism of these mutations were elucidated by solving the structures of PpHDC C57S and C57S/C101V/C282V mutants by X-ray crystallography. In the crystal structures, two symmetry-related PpHDC molecules form a domain-swapped homodimer. The side chain of S57 is solvent exposed in the structure, indicating that the C57S mutation eliminates chemical oxidation or disulfide bond formation with a free thiol group, thereby providing greater stability. Residues 101 and 282 form hydrophobic interactions with neighboring hydrophobic residues. Mutations C101V and C282V enhanced thermostability of PpHDC by filling a cavity present in the hydrophobic core (C101V) and increasing hydrophobic interactions.

Abstract
An enzyme showing l-histidine oxidase (HisO) activity by the formation of hydrogen peroxide was newly purified from Achromobacter sp. TPU 5009. This enzyme was found to be a heterodimer of two proteins (molecular mass, 53.8 and 58.3 kDa), the partial determination of which indicated they are homologs of l-histidine ammonia-lyase (AchHAL) and urocanate hydratase (AchURO). The enzyme was stable in a pH range of 5.0-11.0, with >90% of the original activity maintained below 60°C at pH 7.0. To characterize AchHAL and AchURO, each of their genes was cloned and expressed in a heterologous expression system. Heterologous AchHAL catalyzed the elimination of the α-amino group of l-histidine to urocanate and ammonia, while heterologous AchURO catalyzed the hydration of urocanate to imidazolone propionate. Since imidazolone propionate is highly unstable in the presence of oxygen at neutral pH, it was immediately decomposed and hydrogen peroxide was non-enzymatically produced. Our results indicate that this natural enzyme showing apparent HisO activity is composed of AchHAL and AchURO, which formed hydrogen peroxide after the spontaneous decomposition of imidazolone propionate.

Abstract
Carbon black nanoparticles (CBNPs) are core component of fine particulate matter (PM2.5) in the atmosphere. It was reported that the particle in the atmosphere with smaller size and the larger the specific surface area are easier to reach the deep respiratory tract or even the alveoli through the respiratory barrier and cause lung injury. Therefore, it has been believed that ultrafine or nanometer particles with more toxic than those with larger particle sizes. Moreover, it was confirmed that CBNPs could induce inflammation, oxidative stress and changes in cell signaling and gene expression in mammalian cells and organs. However, the cytotoxicity mechanism of them has been uncertain so far. The aim of the present study was to explore the underlying mechanism of cytotoxicity induced by CBNPs on A549 cells. In the current research, the viabilities of A549 cells were detected by Cell Counting Kit-8 (CCK-8) assay. The further metabolomics studies were conducted to detect the cytotoxic effect of CBNPs on A549 cells with an IC50 value of 70 μg/mL for 48 h. Potential differential compounds were identified and quantified using a novel on-line acquisition method based on ultra-liquid chromatography quadrupole time-of-flight mass spectrometry(UHPLC-Q-TOF/MS). The cytotoxicity mechanism of CBNPs on A549 cells was evaluated by multivariate data analysis and statistics. As a result, a total of 32 differential compounds were identified between CBNPs exposure and control groups. In addition, pathway analysis showed the metabolic changes were involved in the tricarboxylic acid (TCA) cycle, alanine, aspartate and glutamate metabolism, histidine metabolism and so on. It is also suggested that CBNPs may induce cytotoxicity by affecting the normal process of energy metabolism and disturbing several vital signaling pathways and finally induce cell apoptosis.
