Charton, Lennart published the artcilePlant peroxisomal solute transporter proteins, Recommanded Product: (S)-2-hydroxysuccinic acid, the main research area is review peroxisomal membrane ABC transporter.

Plant peroxisomes are unique subcellular organelles which play an indispensable role in several key metabolic pathways, including fatty acid β-oxidation, photorespiration, and degradation of reactive oxygen species. The compartmentalization of metabolic pathways into peroxisomes is a strategy for organizing the metabolic network and improving pathway efficiency. An important prerequisite, however, is the exchange of metabolites between peroxisomes and other cell compartments. Since the first studies in the 1970s scientists contributed to understanding how solutes enter or leave this organelle. This review gives an overview about our current knowledge of the solute permeability of peroxisomal membranes described in plants, yeast, mammals and other eukaryotes. In general, peroxisomes contain in their bilayer membrane specific transporters for hydrophobic fatty acids (ABC transporter) and large cofactor mols. (carrier for ATP, NAD and CoA). Smaller solutes with mol. masses below 300-400 Da, like the organic acids malate, oxaloacetate, and 2-oxoglutarate, are shuttled via non-selective channels across the peroxisomal membrane. In comparison to yeast, human, mammals and other eukaryotes, the function of these known peroxisomal transporters and channels in plants are discussed in this review.

Schiffner, Julia A. published the artcileEnantioselective Fujiwara-Moritani Indole and Pyrrole Annulations Catalyzed by Chiral Palladium(II)-NicOx Complexes, SDS of cas: 50966-69-3, the main research area is pyridinecarboxylate oxazolinyl preparation chiral ligand Fujiwara Moritani annulation; indole pyrrole alkenyl preparation asym intramol Fujiwara Moritani cyclization.

The catalytic asym. Fujiwara-Moritani ring closures of several indole- and pyrrole-based cyclization precursors, e.g. I (R1 = H, R12 = benzo; X = CH2, CH2CH2; R2 = Me, Ph), are reported. These unprecedented oxidative palladium(II)-catalyzed annulations allow for the formation of a stereogenic quaternary carbon atom, and decent levels of enantiocontrol are seen in 5-exo-trig cyclizations (54% ee for an indole and 76% ee for a pyrrole) while 6-exo-trig ring closures afford essentially racemic material. Novel oxazoline ligands with a nicotine platform (NicOx) are pivotal for good catalytic turnover as conventional PyOx ligands failed to produce acceptable chem. yields. The preparation of these NicOx ligands II (R3 = i-Pr, t-Bu, PhCH2; R4 = Me, Et, F3CCH2) as well as the syntheses of the cyclization precursors, e.g. I, are described in detail.

Wang, Liying published the artcileDevelopment of sugarcane resource for efficient fermentation of exopolysaccharide by using a novel strain of Kosakonia cowanii LT-1, Synthetic Route of 59-23-4, the main research area is sugarcane fermentation exopolysaccharide Kosakonia cowanii; Exopolysaccharide; Kosakonia cowanii LT-1; Non-food fermentation; Sugarcane juice; Transcriptome sequencing.

This work focuses on the development of non-food fermentation for the cost-effective biosynthesis of exopolysaccharide (EPS) by using a new strain of Kosakonia cowanii LT-1. This novel strain more efficiently utilizes sucrose for EPS production than other glycosyl donors. Comparative transcriptomic anal. is used to understand EPS synthesis promotion and the effects of sucrose on EPS biosynthesis. We speculate that ATP-binding cassette transporter, phosphotransferase, and two-component systems may be the most essential factors for EPS biosynthesis. The enhanced oxidative phosphorylation increases the synthesis rate of ATP to satisfy the energy demands for EPS production with sucrose as the substrate. Sugarcane juice, a cheap raw material, could improve the EPS yield in batch fermentation and achieve approx. 29.66% cost savings for substrate. Our work presents a promising non-food fermentation approach for the synthesis of high-value industrial products.

Bolle, Jennifer published the artcileIsomeric effects in structure formation and dielectric dynamics of different octanols, Related Products of alcohols-buliding-blocks, the main research area is octanol cluster aggregate hydrogen bond supramol structure.

The understanding of the microstructure of associated liquids promoted by hydrogen-bonding and constrained by steric hindrance is highly relevant in chem., physics, biol. and for many aspects of daily life. In this study we use a combination of X-ray diffraction, dielec. spectroscopy and mol. dynamics simulations to reveal temperature induced changes in the microstructure of different octanol isomers, i.e., linear 1-octanol and branched 2-, 3- and 4-octanol. In all octanols, the hydroxyl groups form the basis of chain-, cyclic- or loop-like bonded structures that are separated by outwardly directed alkyl chains. This clustering is analyzed through the scattering pre-peaks observed from X-ray scattering and simulations. The charge ordering which pilots OH aggregation can be linked to the strength of the Debye process observed in dielec. spectroscopy. Interestingly, all methods used here converge to the same interpretation: as one moves from 1-octanol to the branched octanols, the cluster structure evolves from loose large aggregates to a larger number of smaller, tighter aggregates. All alcs. exhibit a peculiar temperature dependence of both the pre-peak and Debye process, which can be understood as a change in microstructure promoted by chain association with increased chain length possibly assisted by ring-opening effects. All these results tend to support the intuitive picture of the entropic constraint provided by branching through the alkyl tails and highlight its capital entropic role in supramol. assembly.

Chen, Yi published the artcileThe O1/H3-preferred 1:1 H-bonding and the electron-cloud migration induced by H-bonding or non-specific interactions: A systematic study on the interactions between dimethyl phthalate and 1-, 2- or 3-alkanol (C2-C6), Name: 3-Pentanol, the main research area is dimethyl phthalate aliphatic alc hydrogen bond IR spectra.

H-bonding and non-specific interactions between di-Me phthalate (DMP) and different human body substances were considered to be mainly responsible for various health dysfunctions. However, the manner of H-bonding and the adaptability of the structure of DMP that may underpin the H-bonding/non-specific interactions have been difficult to assess and remain elusive. In this study, we set out to gain an insight into the subjects above through a systematic investigation on the interactions between DMP and 1-, 2- or 3-alkanol (C2 – C6). We calculated the H-bond distances, the C=O and C-O bond lengths and other selected structural essentials at B3LYP 6-311G(d) level. We recorded the IR spectra Band I and Band II of C=O of DMP when dissolving DMP into 11 different alkanol/n-Hexane binary solvent systems. We created and fit the equations to delineate the dependence of the absorption intensity ratio of Band II to Band I (AII/AI) on the volume-ratio of the alkanol component (x). Based on the equations, we obtained the percent of the major alkanol associates (-p), the binding constant of the 1:1 and 1:2 DMP-alkanol complexes (K1 and K2) and the ratio of the molar absorptivity of H-bonded C=O to the molar absorptivity of non-bonded C=O (εhb/εns). The -p, K1, K2 and εhb/εns values confirmed the calculated results. It can be concluded that H-bonds mainly form the 1:1 complexes at O1 and H3, leading to species O5-H1···O1 = C1 for 3-alkanols and species O5-H1···O1 = C1 and Ph-H3···O5 for 2-alkanols. The differences of the affinity of H-bonding were mainly attributed to the steric hindrance and to a lesser extent to the hydrophobic interactions and the multi-H-bond cooperativity. The electron-cloud of the DMP mol. was supposed to migrate mainly in the E1 or E4 mode to adapt to the H-bonding or non-specific interactions, resp.

Khedri, Zohrab published the artcileThermodynamic Properties of 1-Hexyl-3-methylimidazolium Nitrate and 1-Alkanols Mixtures: PC-SAFT Model, Category: alcohols-buliding-blocks, the main research area is thermodn property PCSAFT hexylmethylimidazolium nitrate binary mixture alkanol.

To study the type, nature, and amount of interactions in binary systems including 1-hexyl-3-methylimidazolium nitrate ([Hmim][NO3]) ionic liquid and a homologous series of 1-alkanols (1-hexanol up to 1-decanol), some thermophys. properties via d. and viscosity measurements were calculated at temperatures of 293.15-323.15 K. Also, to study the behavior of systems with temperature, values of the thermal expansion coefficient, α, excess thermal expansion coefficient, αE, isothermal coefficient of excess molar enthalpy, (∂HEm/∂P)T,x, and partial molar volume, V̅i, for five binary mixtures at various temperatures were calculated Findings demonstrate that strong interactions between the mixture components occur and intermol. forces become weaker with the increase in the length of the alc. chain and temperature For a theor. study of mentioned mixtures, perturbed-chain statistical associating fluid theory was implemented. The d. and partial molar volume of mixtures were correlated and predicted by this theory, and the results show that outcomes are fairly consistent with the exptl. data.

Almasi, Mohammad published the artcileKirkwood-Buff Integrals, Excess Volume, and Preferential Solvation in Pentanoic Acid/(C5-C10) 1-Alkanol Binary Mixtures, Product Details of C8H18O, the main research area is Kirkwood Buff integral excess volume solvation pentanoic acid alkanol.

In order to study the nature, type, and magnitude of interactions in the binary mixtures of pentanoic acid and a series of 1-alkanols from 1-pentanol up to 1-decanol, Kirkwood integrals along with the exptl. methods have been used and reported at T = 298.15 K. Neg. values of VEm, Gii, Gij, Δnii, Δnij, and δii and pos. values of Gij, Δnij, and δij indicate the fact that in the mixtures the tendency of the unlike mol. components to form the new interactions and stay together is much higher than the pure state. Investigating the changes in the calculated quantities for different mixtures shows that with the increase in the length of the alc. chain the tendency of the heterogeneous mols. to interact with each other decreases. Variations in the VEm values are in the same direction as the Kirkwood integrals, and mentioned data for binary systems are reported for the first time.

Almasi, Mohammad published the artcileThermodynamic study of interactions between 1-alkanol and butanone, Formula: C8H18O, the main research area is thermodn Kirkwood Buff model alkanol butanone mixture solvation structure.

To obtain the new perspectives on the mol. interactions in the binary systems of butanone and a homologous series of 1-alkanol from 1-pentanol up to 1-decanol, these mixtures were studied using the Kirkwood-Buff (KB) formalism and preferential solvation anal. The results were confirmed using the exptl. excess molar volumes. KB integrals Gij, the excess or deficit number Δnij, and solvation coefficients δij are reported here. Anal. of obtained data regarding the KB formalism and preferential solvation reveals that interactions strength in mixtures depends on the butanone concentration and size of 1-alkanol. Also, interactions between similar mols. are remarkable and become stronger as the length of the alc. increases. Furthermore, mixtures structure was studied using the concentration-concentration structure factor, SCC(0). Results from application of this parameter show that the homo-coordination occurs in solutions Steric effects lead to the stronger orientations in the mentioned mixtures

Lee, Richard G. published the artcileCardiolipin is required for membrane docking of mitochondrial ribosomes and protein synthesis, Application of (S)-2-hydroxysuccinic acid, the main research area is cardiolipin mitochondrial ribosome protein synthesis membrane docking; Cardiolipin; Mitochondrial membrane; Mitochondrial ribosomes; Protein synthesis.

The mitochondrial inner membrane contains a unique phospholipid known as cardiolipin (CL), which stabilizes the protein complexes embedded in the membrane and supports its overall structure. Recent evidence indicates that the mitochondrial ribosome may associate with the inner membrane to facilitate co-translational insertion of the hydrophobic oxidative phosphorylation (OXPHOS) proteins into the inner membrane. We generated three mutant knockout cell lines for the CL biosynthesis gene Crls1 to investigate the effects of CL loss on mitochondrial protein synthesis. Reduced CL levels caused altered mitochondrial morphol. and transcriptome-wide changes that were accompanied by uncoordinated mitochondrial translation rates and impaired respiratory chain supercomplex formation. Aberrant protein synthesis was caused by impaired formation and distribution of mitochondrial ribosomes. Reduction or loss of CL resulted in divergent mitochondrial and endoplasmic reticulum stress responses. We show that CL is required to stabilize the interaction of the mitochondrial ribosome with the membrane via its association with OXA1 (also known as OXA1L) during active translation. This interaction facilitates insertion of newly synthesized mitochondrial proteins into the inner membrane and stabilizes the respiratory supercomplexes.
