To investigate the variations in gene expression in grass carp under high-temperature stress, two libraries were constructed from a high-temperature treatment group (T33) and a control group (T27) and sequenced using Illumina sequencing technol. The results showed that sequencing generated a total of 279,398,348 raw reads, approx. 40.7-51.8 M clean reads were obtained from each library, and the percentage of uniquely mapped transcripts ranged from 80.13 to 84.58%. A total of 260 differentially expressed genes (DEGs) were identified under high-temperature stress, among which 84 genes were upregulated and 176 genes were downregulated. Ten DEGs were randomly selected for quant. RT-PCR (qRT-PCR) anal., and the results confirmed that the transcriptome anal. was reliable. Furthermore, the DEGs were subjected to Gene Ontol. (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment anal., and the results showed that most of the DEGs were involved in protein, lipid and carbohydrate metabolism Moreover, plasma urea nitrogen (Urea) and triglyceride (TG) contents were significantly lower in the high-temperature treatment group than in the control group (P < 0.01). In summary, these results indicated that high-temperature stress could inhibit protein synthesis, decrease fatty acid synthesis, and weaken carbohydrate metabolism in juvenile grass carp. This study involved multiple reactions and reactants, such as (4-Formyl-5-hydroxy-6-methylpyridin-3-yl)methyl dihydrogen phosphate (cas: 54-47-7HPLC of Formula: 54-47-7).

Improving the activity and synergistic catalysis of L-aspartate β-decarboxylase by arginine introduction on the surface was written by Hao, Mingzhu;Cui, Ruizhi;Zhu, Xiaoqing;Han, Laichuang;Zhou, Zhemin;Liu, Zhongmei. And the article was included in Catalysis Science & Technology in 2022.HPLC of Formula: 54-47-7 The following contents are mentioned in the article:

Decarboxylase typically catalyzes reactions under acidic conditions, which is the drawback for its synergistic catalysis with other enzymes because most enzymes catalyze reactions under near neutral conditions. Improving the activity of decarboxylase under near neutral conditions will greatly contribute to its application in synthetic biol. and multienzyme cascade catalysis for the production of chem. compounds, in which many enzymes need to function cooperatively. We choose L-aspartate β-decarboxylase (ASD) that is widely applied in industry to implement the semirational design strategy. The catalytic ability of ASD was successfully improved by substituting glutamic acid for arginine at the 88th position on the surface. The specific activity of an E88R variant was increased to 481 U mg-1 compared to 230 U mg-1 for the wild type. Furthermore, the stability over a range of pH 3.0-8.0 was dramatically increased. The catalytic ability and synergy with other enzymes of the E88R variant were demonstrated in a triple-enzyme system for L-alanine production, and the productivity was increased from 28.2 g (L-1 h-1) to 43.3 g (L-1 h-1). The pH-dependent inactivation of ASD was relieved, and this strategy could be expanded to the decarboxylase family. Addnl., the variant obtained here also shows promising prospects for application in industry.

Methionine γ-lyase (MGL) is a pyridoxal 5â€?phosphate-dependent enzyme catalyzing γ-elimination in L-methionine. Pyridoxal 5â€?phosphate-dependent enzymes have unique spectral properties that allow to monitor sequential formation and decomposition of various intermediates via the detection of absorbance changes. The kinetic mechanism of the γ-elimination reaction catalyzed by Citrobacter freundii MGL was elucidated here by fast stopped-flow kinetic anal. Single-wavelength detection of characteristic absorbance changes enabled us to compare transformations of intermediates in the course of the reaction with different substrates. The influence of various γ-substituents in the substrate on the formation of key intermediates was estimated Kinetic isotope effects of α- and β-protons were determined using deuterium-substituted L-methionine. Contributions of amino acid residues Tyr113 and Tyr58 located in the active site on the formation and decomposition of reaction intermediates were identified too. α-Aminocrotonate formation is the rate-limiting step of the enzymic γ-elimination reaction. Kinetic isotope effects strongly support concerted reaction mechanisms of transformation between an external aldimine and a ketimine intermediate as well as a ketimine intermediate and an unsaturated ketimine.

The rising awareness of environmental protection has triggered bio-based materials to replace the traditional petrochem. plastics. Putrescine as 1,4-diaminobutane is an important monomer of polyamide (PA) and uses in the sustainable chem. industry. Herein, a time-effective whole cell bioconversion of L-arginine to putrescine was developed, which has applied the key enzymes (i.e., SpeA and SpeB) from the arginine decarboxylase (ADC) pathway. The synergetic collaboration of both enzymes was examined from the different combination of plasmids among 4 Escherichia coli chassis. The optimal reaction condition was at pH 9 with 1 mM pyridoxal-5�phosphate (PLP) and 10 mM magnesium, thus 90% conversion was obtained using an all-in-one plasmid with equal protein of SpeA and SpeB in BL21(DE3). The enzymic kinetics demonstrated the higher k_cat of SpeA (1212 s^-1) than that of SpeB (418 s^-1), while severe inhibition of putrescine on SpeA (KI = 8.61 mM), thus it was disadvantage using the surface display of enzyme. To prevent the feedback-inhibition by product, a 2-step enzymic reaction with cold treatment was conducted. Finally, the putrescine was achieved 17.1 g/L with the productivity of 8.56 g/L/h under 86% conversion of 50 g/L -arginine-HCl, which is an effective approach to obtain high putrescine titer.

Structural and Functional Analysis of the Pyridoxal Phosphate Homeostasis Protein YggS from Fusobacterium nucleatum. was written by He, Shanru;Chen, Yuanyuan;Wang, Lulu;Bai, Xue;Bu, Tingting;Zhang, Jie;Lu, Ming;Ha, Nam-Chul;Quan, Chunshan;Nam, Ki Hyun;Xu, Yongbin. And the article was included in Molecules (Basel, Switzerland) in 2022.Formula: C8H10NO6P The following contents are mentioned in the article:

Pyridoxal 5′-phosphate (PLP) is the active form of vitamin B6, but it is highly reactive and poisonous in its free form. YggS is a PLP-binding protein found in bacteria and humans that mediates PLP homeostasis by delivering PLP to target enzymes or by performing a protective function. Several biochemical and structural studies of YggS have been reported, but the mechanism by which YggS recognizes PLP has not been fully elucidated. Here, we report a functional and structural analysis of YggS from Fusobacterium nucleatum (FnYggS). The PLP molecule could bind to native FnYggS, but no PLP binding was observed for selenomethionine (SeMet)-derivatized FnYggS. The crystal structure of FnYggS showed a type III TIM barrel fold, exhibiting structural homology with several other PLP-dependent enzymes. Although FnYggS exhibited low (&lt;35%) amino acid sequence similarity with previously studied YggS proteins, its overall structure and PLP-binding site were highly conserved. In the PLP-binding site of FnYggS, the sulfate ion was coordinated by the conserved residues Ser201, Gly218, and Thr219, which were positioned to provide the binding moiety for the phosphate group of PLP. The mutagenesis study showed that the conserved Ser201 residue in FnYggS was the key residue for PLP binding. These results will expand the knowledge of the molecular properties and function of the YggS family. This study involved multiple reactions and reactants, such as (4-Formyl-5-hydroxy-6-methylpyridin-3-yl)methyl dihydrogen phosphate (cas: 54-47-7Formula: C8H10NO6P).

Study on zinc accumulation, bioavailability, physicochemical and structural characteristics of brown rice combined with germination and zinc fortification was written by Zhang, Bao;Wang, Ru-Meng;Chen, Pin;He, Ting-Shi;Bai, Bin. And the article was included in Food Research International in 2022.Related Products of 54-47-7 The following contents are mentioned in the article:

In this work, the combination treatment of zinc sulfate fortification and germination was used to increase zinc content and bioavailability of brown rice. The zinc content in brown rice during germination time of 10-34 h gradually increased with the increase of zinc sulfate concentration (0-100 mg/L). Brown rice with zinc fortified concentration of 25 mg/L and germinated for 28 h was recommended, which reached the maximum (26.31%) of zinc bioavailability and met the requirements of recommended dietary intake (RDA) of zinc. The physicochem. and structural characteristics of brown rice under different treatment conditions were compared. As the germination time prolonged, the germination rate (%), total phenol content, 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging rate (%) and Gamma-aminobutyric acid content of fortified or unfortified brown rice increased, while the phytic acid content decreased. The fortification treatment improved total phenol content and antioxidant activity of germinated brown rice. The crystalline structure of brown rice was destroyed during germination, but no significant change of crystalline structure caused by zinc sulfate fortification was found. These results could provide valuable reference for the application of germination in the field of brown rice fortification and the preparation of zinc-rich germinated brown rice products.

2-Aminoacrylate stress damages diverse PLP-dependent enzymes in vivo was written by Shen, Wangchen;Borchert, Andrew J.;Downs, Diana M.. And the article was included in Journal of Biological Chemistry in 2022.Quality Control of (4-Formyl-5-hydroxy-6-methylpyridin-3-yl)methyl dihydrogen phosphate The following contents are mentioned in the article:

Pyridoxal 5′-phosphate (PLP) is an essential cofactor for a class of enzymes that catalyze diverse reactions in central metabolism The catalytic mechanism of some PLP-dependent enzymes involves the generation of reactive enamine intermediates like 2-aminoacrylate (2AA). 2AA can covalently modify PLP in the active site of some PLP-dependent enzymes and subsequently inactivate the enzyme through the formation of a PLP-pyruvate adduct. In the absence of the enamine/imine deaminase RidA, Salmonella enterica experiences 2AA-mediated metabolic stress. Surprisingly, PLP-dependent enzymes that generate endogenous 2AA appear to be immune to its attack, while other PLP-dependent enzymes accumulate damage in the presence of 2AA stress; however, structural determinants of 2AA sensitivity are unclear. In this study, we refined a mol. method to query proteins from diverse systems for their sensitivity to 2AA in vivo. This method was then used to examine active site residues of Alr, a 2AA-sensitive PLP-dependent enzyme, that affect its sensitivity to 2AA in vivo. Unexpectedly, our data also showed that a low level of 2AA stress can persist even in the presence of a functional RidA. In summary, this study expands our understanding of 2AA metabolism and takes an initial step toward characterizing the structural determinants influencing enzyme susceptibility to damage by free 2AA.
