Snapshots during the catalytic cycle of a histidine acid phytase reveal an induced-fit structural mechanism

Highly engineered phytases, which sequentially hydrolyze the hexakisphosphate ester of inositol known as phytic acid, are routinely added to the feeds of monogastric animals to improve phosphate bioavailability. New phytases are sought as starting points to further optimize the rate and extent of dephosphorylation of phytate in the animal digestive tract. Multiple inositol polyphosphate phosphatases (MINPPs) are clade 2 histidine phosphatases (HP2P) able to carry out the stepwise hydrolysis of phytate. MINPPs are not restricted by a strong positional specificity making them attractive targets for development as feed enzymes. Here, we describe the characterization of a MINPP from the Gram-positive bacterium Bifidobacterium longum (BlMINPP). BlMINPP has a typical HP2P-fold but, unusually, possesses a large alpha-domain polypeptide insertion relative to other MINPPs. This insertion, termed the U-loop, spans the active site and contributes to substrate specificity pockets underpopulated in other HP2Ps. Mutagenesis of U-loop residues reveals its contribution to enzyme kinetics and thermostability. Moreover, four crystal structures of the protein along the catalytic cycle capture, for the first time in an HP2P, a large ligand-driven alpha-domain motion essential to allow substrate access to the active site. This motion recruits residues both downstream of a molecular hinge and on the U-loop to participate in specificity subsites, and mutagenesis identified a mobile lysine residue as a key determinant of positional specificity of the enzyme. Taken together, these data provide important new insights to the factors determining stability, substrate recognition, and the structural mechanism of hydrolysis in this industrially important group of enzymes.

Factor XII/XIIa inhibitors: Their discovery, development, and potential indications

Coagulation factor XII (FXII), a S1A serine protease, was discovered more than fifty years ago. However, its in vivo functions and its three-dimensional structure started to be disclosed in the last decade. FXII was found at the crosstalk of several physiological pathways including the intrinsic coagulation pathway, the kallikrein-kinin system, and the immune response. The FXII inhibition emerges as a therapeutic strategy for the safe prevention of artificial surface-induced thrombosis and in patients suffering from hereditary angioedema. The anti-FXII antibody garadacimab discovered by phage-display library technology is actually under phase II clinical evaluation for the prophylactic treatment of hereditary angioedema. The implication of FXII in neuro-inflammatory and neurodegenerative disorders is also an emerging research field. The FXII or FXIIa inhibitors currently under development include peptides, proteins, antibodies, RNA-based technologies, and, to a lesser extent, small-molecular weight inhibitors. Most of them are proteins, mainly isolated from hematophagous arthropods and plants. The discovery and development of these FXII inhibitors and their potential indications are discussed in the review. (c) 2020 Elsevier Masson SAS. All rights reserved.

Synthesis and Evaluation of Maleic Anhydride-Methyl Oleate Copolymer as a Corrosion Inhibitor for C-steel in 0.1 M HCl Solution

The present study investigated the synthesis of a copolymer of maleic anhydride and an ester of oleic acid. Poly (maleic anhydride-co-methyl oleate) was prepared via the free radical polymerization of maleic anhydride with methyl oleate. The prepared copolymer was Characterized via FTIR and GPC and thermal analyses (TGA and DTA). TGA demonstrated that the prepared copolymer was thermally stable up to 146 degrees C. Electrochemical measurement tests, including potentiodynamic polarization tests, revealed that the prepared copolymer was successfully applied as an organic corrosion inhibitor for C-steel in 0.1 M HCl solution at 298 K, 308 K, 318 K and 328 K. Potentiodynamic polarization measurements revealed that this copolymer was a mixed-type corrosion inhibitor. Its inhibition efficiency was measured on the basis of potentiodynamic polariaztion curves via the electrochemical technique. Results demonstrated that the corrosion inhibition efficiency of poly(maleic anhydride-comethyl oleate) increased with concentration and decreased with increasing temperature. Inhibition efficiency reached 94.8% with 20 ppm poly (maleic anhydride-co-methyl oleate) at 298 K. The adsorption of this copolymer on the C-steel surface was chemical adsorption and obeyed the Langmuir adsorption isotherm.

Effect of Soybean biodiesel and Copper coated Zinc oxide Nanoparticles on Enhancement of Diesel Engine Characteristics

In the present research, the influence of metallic copper-coated zinc oxide (Cu-ZnO) nanoparticles (NPs) and soybean biodiesel on the improvement in efficiency and emission characteristics of a VCR engine are examined. The soybean methyl ester (SBME) was produced utilizing the transesterification reaction. Several characterization experiments were performed to determine the shape, scale, and contents of the synthesized Cu-ZnO NPs. The Cu-ZnO NPs and SDBS surfactant were steadily distributed utilizing the ultrasonic vibration in SBME25-diesel at three stages (25, 50, and 75 ppm). The prepared physicochemical properties of fuels are comparable with ASTM requirements. In comparison to SBME25, nanofuel mixtures displayed better fuel properties. A compression ratio of 21.5 was used and a comparison was made with the SBME25. The SBME25Cu-ZnO50 combination and the CR 21.5 have illustrated an increase in overall engine characteristics. For the SBME25Cu-ZnO50 mixture, BTE and HRR raised by 16.1% and 19.2%, BSFC and ID dropped by 18.9% and 14.6%, and hydrocarbon, carbon monoxide, and smoke emissions lowered by 24.1%, 34.5%, and 16.8%. In all nanofuel blends, the oxide of nitrogen raised owing to a higher oxygen supply to the CC.

NiCoO2@CeO2 Nanoboxes for Ultrasensitive Electrochemical Immunosensing Based on the Oxygen Evolution Reaction in a Neutral Medium: Application for Interleukin-6 Detection

The development of highly active electrocatalytic labels is important for constructing sensitive electrochemical immunosensors. Great progress has been made in developing non-noble-metal nanocatalysts toward the oxygen evolution reaction (OER) in the past decade, but non-noble-metal OER nanocatalysts have not been explored as electrocatalytic labels for immunosensing. Herein, we report NiCoO2@CeO2 nanoboxes (NBs) as novel electrocatalytic labels for ultrasensitive immunosensing based on the excellent OER activity of NiCoO2@CeO2 NBs in a neutral solution. The synthesis of NiCoO2@CeO2 NBs involves Ni2+ exchange and heat treatment of ZIF-67 nanocubes to produce NiCoO2 NBs, followed by the growth of CeO2 nanoparticles on the surface of NiCoO2 NBs. The NiCoO2@CeO2 NBs offer superior OER activity to NiCoO2 NBs because of the synergetic effect between NiCoO2 NBs and CeO2 nanoparticles. The formation of ester-like bridging between CeO2 and the carboxylic groups of antibody enables direct immobilization of the antibody on the NiCoO2@CeO2 surface. A sandwich-type electrochemical immunosensor using NiCoO2@CeO2 NBs as electrocatalytic labels features a broad linear range for interleukin-6 detection from 2.5 x 10(-5) to 10 ng mL(-1), with a low detection limit of 7 fg mL(-1). Our work lays the foundation for developing electrochemical immunosensors and aptasensors based on non-noble-metal OER electrocatalysts.
