Abstract
Bacillus subtilis is an industrially important microorganism that is often used as a microbial cell factory for the production of recombinant proteins due to its food safety, rapid growth, and powerful secretory capacity. However, the lack of data on functional genes related to recombinant protein production has hindered the further development of B. subtilis cell factories. Here, a strategy combining genome-wide CRISPRi screening and targeted CRISPRa activation to enhance recombinant protein expression is proposed. First, a CRISPRi library covering a total of 4225 coding genes (99.7%) in the B. subtilis genome and built the corresponding high-throughput screening methods is constructed. Twelve key genes for recombinant protein expression are identified, including targets without relevant functional annotations. Meanwhile, the transcription of recombinant protein genes by CRISPRa is up-regulated. These screened or selected genes can be easily applied to metabolic engineering by constructing sgRNA arrays. The relationship between differential pathways and recombinant protein expression in engineered strains by transcriptome analysis is also revealed. High-density fermentation and generalisability validation results prove the reliability of the strategy. This method can be extended to other industrial hosts to support functional gene annotation and the design of novel cell factories.

Abstract
Nanochaperones (nChaps) have significant potential to inhibit protein aggregation and assist in protein refolding. The interaction between nChaps and proteins plays an important role in nChaps performing chaperone-like functions, but the interaction mechanism remains elusive. In this work, a series of nChaps with tunable hydrophilic-hydrophobic surfaces are prepared, and the process of nChaps-assisted denatured protein refolding is systematically explored. It is found that an appropriate hydrophilic-hydrophobic balance on the nChap surface is critical for enhancing protein renaturation. This is because only the optimal interaction between nChap and protein can simultaneously guarantee the suitable capture and sufficient release of client proteins. The findings in this work will provide an effective reference for the design of nChaps and contribute to the development of the potential of nChaps in the future.

Abstract
The proper functioning of any protein depends on its three dimensional conformation which is achieved by the accurate folding mechanism. Keeping away from the exposed stress conditions leads to cooperative unfolding and sometimes partial folding, forming the structures like protofibrils, fibrils, aggregates, oligomers, etc. leading to several neurodegenerative diseases like Parkinson's disease, Alzheimer's, Cystic fibrosis, Huntington, Marfan syndrome, and also cancers in some cases, too. Hydration of proteins is necessary, which may be achieved by the presence of organic solutes called osmolytes within the cell. Osmolytes belong to different classes in different organisms and play their role by preferential exclusion of osmolytes and preferential hydration of water molecules and achieves the osmotic balance in the cell otherwise it may cause problems like cellular infection, cell shrinkage leading to apoptosis and cell swelling which is also the major injury to the cell. Osmolyte interacts with protein, nucleic acids, intrinsically disordered proteins by non-covalent forces. Stabilizing osmolytes increases the Gibbs free energy of the unfolded protein and decreases that of folded protein and vice versa with denaturants (urea and guanidinium hydrochloride). The efficacy of each osmolyte with the protein is determined by the calculation of m value which reflects its efficiency with protein. Hence osmolytes can be therapeutically considered and used in drugs.

Abstract
The β1-subunit of the Na+/K+-ATPase is a cell membrane protein, beyond its classic functions, it is also a cell adhesion molecule. β1-subunits on the lateral membrane of dog kidney epithelial cells trans-interact with β1-subunits from another neighboring cells. The β-β interaction is essential for the formation and stabilization of intercellular junctions. Previous studies on site-directed mutagenesis and in silico revealed that the interaction interface involves residues 198-207 and 221-229. However, it is necessary to report the interaction interface at the structural level experimentally. Here, we describe the successful cloning, overexpression in E. coli, and purification of the extracellular domain of the β1-subunit from inclusion bodies. Experimental characterization by size exclusion chromatography and DLS indicated similar hydrodynamic properties of the protein refolded. Structural analysis by circular dichroism and Raman spectroscopy revealed the secondary structures in the folded protein of type β-sheet, α-helix, random coil, and turn. We also performed β1-β1 interaction assays with the recombinant protein, showing dimers' formation (6xHisβ1-β1). Given our results, the recombinant extracellular domain of the β1-subunit is highly similar to the native protein, therefore the current work in our laboratory aims to characterize at the atomic level the interaction interface between EDβ1.

Abstract
Most of the neurological disorders in the brain are caused by the abnormal buildup of misfolded or aggregated proteins. Osmolytes are low molecular weight organic molecules usually built up in tissues at a quite high amount during stress or any pathological condition. These molecules help in providing stability to the aggregated proteins and protect these proteins from misfolding. Alzheimer’s disease (AD) is the uttermost universal neurological disorder that can be described by the deposition of neurofibrillary tangles, aggregated/misfolded protein produced by the amyloid β-protein (Aβ). Osmolytes provide stability to the folded, functional form of a protein and alter the folding balance away from aggregation and/or degradation of the protein. Moreover, they are identified as chemical chaperones. Brain osmolytes enhance the pace of Aβ aggregation, combine with the nearby water molecules more promptly, and avert the aggregation/misfolding of proteins by providing stability to them. Therefore, osmolytes can be employed as therapeutic targets and may assist in potential drug design for many neurodegenerative and other diseases.

Abstract
Understanding protein aggregation is of utmost importance as it is responsible for causing several neurodegenerative diseases and one of the serious impediments in large-scale biopharmaceutical production. The prion protein is responsible for pathological states in fatal transmissible spongiform conditions, such as Creutzfeldt-Jakob disease and bovine spongiform encephalopathy. The peptide fragment 178-191 of Syrian hamster prion protein is known to be amyloidogenic. Here, we identified the fragment 179CVNITV184 as an aggregation-prone fragment in sheep prion protein. This fragment is conserved sequence among sheep and Syrian hamster prion protein and also falls in the previously identified amyloidogenic sequence. The mechanistic details of the aggregation behavior are analyzed in three different concentrations of urea, arginine, and ethanol. Urea and arginine are found to be aggregation suppressors, but ethanol enhances the protein aggregation through β-sheet formation. We have also analyzed the influence of these osmolyte on water dynamics in the presence of the octamer of this aggregation-prone fragment and correlated this water dynamics with the aggregation behavior of the octamer.

Abstract
Background The GTFB enzyme of the probiotic bacterium Lactobacillus reuteri 121 is a 4,6-α-glucanotransferase of glycoside hydrolase family 70 (GH70; http://www.cazy.org). Contrary to the glucansucrases in GH70, GTFB is unable to use sucrose as substrate, but instead converts malto-oligosaccharides and starch into isomalto-/malto- polymers that may find application as prebiotics and dietary fibers. The GTFB enzyme expresses well in Escherichia coli BL21 Star (DE3), but mostly accumulates in inclusion bodies (IBs) which generally contain wrongly folded protein and inactive enzyme. Methods Denaturation followed by refolding, as well as ncIB preparation were used for isolation of active GTFB protein from inclusion bodies. Soluble, refolded and ncIB GTFB were compared using activity assays, secondary structure analysis by FT-IR, and product analyses by NMR, HPAEC and SEC. Results Expression of GTFB in E. coli yielded > 100 mg/l relatively pure and active but mostly insoluble GTFB protein in IBs, regardless of the expression conditions used. Following denaturing, refolding of GTFB protein was most efficient in double distilled H2O. Also, GTFB ncIBs were active, with approx. 10 % of hydrolysis activity compared to the soluble protein. When expressed as units of activity obtained per liter E. coli culture, the total amount of ncIB GTFB expressed possessed around 180 % hydrolysis activity and 100 % transferase activity compared to the amount of soluble GTFB enzyme obtained from one liter culture. The product profiles obtained for the three GTFB enzyme preparations were similar when analyzed by HPAEC and NMR. SEC investigation also showed that these 3 enzyme preparations yielded products with similar size distributions. FT-IR analysis revealed extended β-sheet formation in ncIB GTFB providing an explanation at the molecular level for reduced GTFB activity in ncIBs. The thermostability of ncIB GTFB was relatively high compared to the soluble and refolded GTFB. Conclusion In view of their relatively high yield, activity and high thermostability, both refolded and ncIB GTFB derived from IBs in E. coli may find industrial application in the synthesis of modified starches.

Abstract
Background: Reteplase is a mutant version of t-PA (tissue plasminogen activator) with prolonged half-life. In the present study, E. coli Top 10 bacteria were utilized in the production of reteplase, which is the nonglycosylated active domain of t-PA. Reteplase gene was ligated into pBAD/gIII plasmid which, allows secretion of this protein in periplasmic space. It would allow the correct formation of disulfide bonds in protein structure. Objectives: This study aimed at expression of reteplase in optimum condition. In this study, the reteplase gene was cloned and expressed in Escherichia coli top 10 as a suitable host cell and its expression was optimized. Materials and Methods: The recombinant plasmid, pET15b/reteplase was digested by NcoI and BamHI restriction enzymes; while pBAD/gIIIA vector was digested by NcoI and BglII. Then the insert and vector were ligated and used for transformation of E. coli Top10 cells by heat shock method. Overnight culture of transformed bacteria was induced by L-arabinose in various concentrations (0.2, 0.02, 0.002, and 0.0002%) and at various temperatures. Results: The obtained recombinant plasmid was sequenced to confirm the presence and correct framing of reteplase gene regarding the expression of reteplase. Maximum production of this enzyme was obtained under the following condition: 0.0002% L-arabinose at 37°C for 2 hours incubation. The purified protein was detected on SDS-PAGE (sodium dodecyl sulfate Polyacrylamide gel electrophoresis) as a 66 kDa band. The concentration of t-PA standard was 1 unit which is equal to 12 µg/mL. The enzymatic activity of samples was measured as 0.8 units compared to the standards. Conclusions: Reteplase was expressed in E. coli Top 10 after activation of pBAD/gIIIA promoter region by arabinose and optimized.

Abstract
Protein folding occurs simultaneously with disulfide bond formation. In general, the in vitro folding of proteins containing disulfide bond(s) is carried out in the presence of redox reagents, such as glutathione, to permit native disulfide pairing to occur. It is well known that the formation of a disulfide bond and the correct tertiary structure of a target protein are strongly affected by the redox reagent used. However, little is known concerning the role of each amino acid residue of the redox reagent, such as glutathione. Therefore, we prepared glutathione derivatives - glutamyl-cysteinyl-arginine (ECR) and arginyl-cysteinyl-glycine (RCG) - and examined their ability to facilitate protein folding using lysozyme and prouroguanylin as model proteins. When the reduced and oxidized forms of RCG were used, folding recovery was greater than that for a typical glutathione redox system. This was particularly true when high protein concentrations were employed, whereas folding recovery using ECR was similar to that of the glutathione redox system. Kinetic analyses of the oxidative folding of prouroguanylin revealed that the folding velocity (K(RCG) = 3.69 × 10(-3) s(-1)) using reduced RCG/oxidized RCG was approximately threefold higher than that using reduced glutathione/oxidized glutathione. In addition, folding experiments using only the oxidized form of RCG or glutathione indicated that prouroguanylin was converted to the native conformation more efficiently in the case of RCG, compared with glutathione. The findings indicate that a positively charged redox molecule is preferred to accelerate disulfide-exchange reactions and that the RCG system is effective in mediating the formation of native disulfide bonds in proteins.

Abstract
Equine lysozyme (EL) is a calcium (Ca)-binding lysozyme and is an intermediary link between non-Ca-binding C-type lysozyme and alpha-lactalbumin. The feature of lysozymes to assemble into the fibrils has recently gained considerable attention for the investigation of the functional properties of these proteins. To study the structural and functional properties of EL, a synthetic gene was cloned and EL was overexpressed in Escherichia coli as a fused protein. The His-tagged recombinant EL was accumulated as inclusion bodies. Up to 50 mg/l of the recombinant EL could be achieved after purification by Ni(2+) affinity chromatography, refolding in the presence of arginine, CM-Sepharose column purification following TEV protease cleavage. The purified protein was functionally active, as determined by the lysozyme activity, proving the proper folding of protein. The purified lysozyme was used for the oligomerisation studies. The protein formed amyloid fibrils during incubation in acidic pH and elevated temperature. The recombinant EL forms two types of fibrils: ring shaped and linear, similar to the native EL.

Abstract
Cyclodextrins with different ring size and ring substituents were tested for recombinant mink and porcine growth hormones aggregation suppression in the refolding process from Escherichia coli inclusion bodies. Methyl-beta-cyclodextrin and 2-hydroxypropyl-beta-cyclodextrin show a positive effect on the aggregation suppression of both proteins. The influence of different methyl-beta-cyclodextrin and 2-hydroxypropyl-beta-cyclodextrin concentrations on the renaturation yield of both growth hormones was investigated. Moreover, methyl-beta-cyclodextrin and 2-hydroxypropyl-beta-cyclodextrin suppress not only folding-related, but also temperature-related aggregates formation of both proteins. Circular dichroism experiments (monitoring of protein solution turbidity by registering high tension voltage) showed that the onset temperature of aggregation of both growth hormones increased with increasing 2-hydroxypropyl-beta-cyclodextrin concentration. In conclusion, cyclodextrins have perspectives in biotechnology of veterinary growth hormones not only for protein production, but also for its storage.

Abstract
Arginine hydrochloride has been used to suppress protein aggregation during refolding and in various other applications. We investigated the structure of hen egg-white lysozyme (HEL) and solvent molecules in arginine hydrochloride solution by X-ray crystallography. Neither the backbone nor side-chain structure of HEL was altered by the presence of arginine hydrochloride. In addition, no stably bound arginine molecules were observed. The number of hydration water molecules, however, changed with the arginine hydrochloride concentration. We suggest that arginine hydrochloride suppresses protein aggregation by altering the hydration structure and the transient binding of arginine molecules that could not be observed.
