Molecular engineering of organophosphate hydrolysis activity from a weak promiscuous lactonase template

Rapid evolution of enzymes provides unique molecular insights into the remarkable adaptability of proteins and helps to elucidate the relationship between amino acid sequence, structure, and function. We interrogated the evolution of the phosphotriesterase from Pseudomonas diminuta (PdPTE), which hydrolyzes synthetic organophosphates with remarkable catalytic efficiency. PTE is thought to be an evolutionarily “young” enzyme, and it has been postulated that it has evolved from members of the phosphotriesterase-like lactonase (PLL) family that show promiscuous organophosphate-degrading activity. Starting from a weakly promiscuous PLL scaffold (Dr0930 from Deinococcus radiodurans), we designed an extremely efficient organophosphate hydrolase (OPH) with broad substrate specificity using rational and random mutagenesis in combination with in vitro activity screening. The OPH activity for seven organophosphate substrates was simultaneously enhanced by up to 5 orders of magnitude, achieving absolute values of catalytic efficiencies up to 10 6 M-1 s-1. Structural and computational analyses identified the molecular basis for the enhanced OPH activity of the engineered PLL variants and demonstrated that OPH catalysis in PdPTE and the engineered PLL differ significantly in the mode of substrate binding.

The effect of homogenization pressure on the flavor and flavor stability of whole milk powder

Flavor is one of the key factors that can limit the application and shelf life of dried dairy ingredients. Many off-flavors are caused during ingredient manufacture that carry through into ingredient applications and decrease consumer acceptance. The objective of this research was to investigate the effect of homogenization pressure on the flavor and flavor stability of whole milk powder (WMP). Whole milk powder was produced from standardized pasteurized whole milk that was evaporated to 50% solids (wt/wt), homogenized in 2 stages with varying pressures (0/0, 5.5/1.4, 11.0/2.8, or 16.5/4.3 MPa), and spray dried. Whole milk powder was evaluated at 0, 3, and 6 mo of storage at 21C. Sensory properties were evaluated by descriptive analysis. Volatile compounds were analyzed by sorptive stir bar extraction with gas chromatography-mass spectrometry. Fat globule size in condensed whole milk and particle size of powders were measured by laser diffraction. Surface free fat, inner free fat, and encapsulated fat of WMP were measured by solvent extractions. Phospholipid content was measured by ultra-high-performance liquid chromatography?evaporative light scattering. Furosine in WMP was analyzed by ultra-high-performance liquid chromatography?mass spectrometry. Increased homogenization pressure decreased cardboard and painty flavors, volatile lipid oxidation compound concentrations, fat globule size in condensed milk, surface free fat, and inner free fat in WMP. Encapsulated fat increased and phospholipid-to-encapsulated fat ratio decreased with higher homogenization pressure. Surface free fat in powders increased cardboard flavor and lipid oxidation. These results indicate that off-flavors were decreased with increased homogenization pressures in WMP due to the decrease in free fat. To decrease off-flavor intensities in WMP, manufacturers should carefully evaluate these parameters during ingredient manufacture.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of 6-Butyltetrahydro-2H-pyran-2-one, you can also check out more blogs about3301-94-8

Application of Threonine Aldolases for the Asymmetric Synthesis of alpha-Quaternary alpha-Amino Acids

We report the synthesis of diverse beta-hydroxy-alpha,alpha-dialkyl-alpha-amino acids with perfect stereoselectivity for the alpha-quaternary center through the action of l- and d-specific threonine aldolases. A wide variety of aliphatic and aromatic aldehydes were accepted by the enzymes and conversions up to >80 % were obtained. In the case of d-selective threonine aldolase from Pseudomonas sp., generally higher diastereoselectivities were observed. The applicability of the protocol was demonstrated by performing enzymatic reactions on preparative scale. Using the d-threonine aldolase from Pseudomonas sp., (2R,3S)-2-amino-3-(2-fluorophenyl)-3-hydroxy-2-methylpropanoic acid was generated in preparative amounts in one step with a diastereomeric ratio >100 favoring the syn-product. A Birch-type reduction enabled the reductive removal of the beta-hydroxy group from (2S)-2-amino-3-hydroxy-2-methyl-3-phenylpropanoic acid to generate enantiopure l-alpha-methyl-phenylalanine via a two-step chemo-enzymatic transformation.

Ripening changes of the chemical composition, proteolysis, volatile fraction and organoleptic characteristics of a white-brined goat milk cheese

In this study, a white-brined cheese made from goat milk (from the Greek native breed Capra prisca) was manufactured using the technology based on Feta cheese-making. The composition, proteolysis, volatiles and sensory properties of this cheese were studied at different ripening days. No significant differences were found for the main physicochemical parameters of the cheese during ripening and storage. Retinol and alpha-tocopherol, the fat-soluble vitamins decreased after 60 d of ripening. Proteolysis, as assessed by measuring the levels of soluble nitrogen, increased with time. Free fatty acids were the most abundant group of chemical compounds found in the cheese. Most of the volatiles (apart from free fatty acids) reached their highest levels after 60 days of ripening. The cheese received satisfactory scores during organoleptic evaluation.

Electronic structure contributions towards the Anomeric effect

The anomeric effect in saccharides, manifested by an unusual stabilization of axial isomers with respect to equatorial ones at one of the carbon atoms in pyranose rings, has been proposed to originate in steric interactions with the lone pair of the pyranoid oxygen atom, or in differences in dipole moments, or in hyperconjugation. Here, we revisit this topic with computational methods, assessing the contribution of various factors towards the anomeric effect on models such as cyclohexanol, tetrahydropyran-2-ol, tetrahydropyran-4-ol, and piperidin-2-ol. Dipole moments, molecular orbitais corresponding to interaction between the lone pairs of the two oxygen, and axial-axial noncovalent interactions are thus considered and their effects estimated.

Design and Discovery of N-(2-Methyl-5?-morpholino-6?-((tetrahydro-2H-pyran-4-yl)oxy)-[3,3?-bipyridin]-5-yl)-3-(trifluoromethyl)benzamide (RAF709): A Potent, Selective, and Efficacious RAF Inhibitor Targeting RAS Mutant Cancers

RAS oncogenes have been implicated in >30% of human cancers, all representing high unmet medical need. The exquisite dependency on CRAF kinase in KRAS mutant tumors has been established in genetically engineered mouse models and human tumor cells. To date, many small molecule approaches are under investigation to target CRAF, yet kinase-selective and cellular potent inhibitors remain challenging to identify. Herein, we describe 14 (RAF709) [ Aversa, et al. Biaryl amide compounds as kinase inhibitors and their preparation. WO 2014151616, 2014 ], a selective B/C RAF inhibitor, which was developed through a hypothesis-driven approach focusing on drug-like properties. A key challenge encountered in the medicinal chemistry campaign was maintaining a balance between good solubility and potent cellular activity (suppression of pMEK and proliferation) in KRAS mutant tumor cell lines. We investigated the small molecule crystal structure of lead molecule 7 and hypothesized that disruption of the crystal packing would improve solubility, which led to a change from N-methylpyridone to a tetrahydropyranyl oxy-pyridine derivative. 14 proved to be soluble, kinase selective, and efficacious in a KRAS mutant xenograft model.
