Abstract
Overproduction of the membrane proteins in Escherichia coli cells is a common approach to obtain sufficient material for their functional and structural studies. However, the efficiency of this process can be limited by toxic effects which decrease the viability of the host and lead to low yield of the product. During the expression of the esterase autotransporter AT877 from Psychrobacter cryohalolentis K5T, we observed significant growth inhibition of the C41(DE3) cells in comparison with the same cells producing other recombinant proteins. Induction of AT877 synthesis also resulted in the elevated expression of a magnesium transporter MgtA and decreased ATP content of the cells. To characterize the response to overexpression of the autotransporter in bacterial cells, we performed a comparative analysis of their proteomic profile by mass spectrometry. According to the obtained data, E. coli cells which synthesize AT877 experience complex stress condition presumably associated with secretion apparatus overloading and improper localization of the recombinant protein. Several response pathways were shown to be activated by AT877 overproduction including Cpx, PhoP/PhoQ, Psp, and σE The obtained results open new opportunities for optimization of the recombinant membrane protein expression in E. coli for structural studies and biotechnological applications.

Abstract
(Deoxy)guanosine-5'-triphosphate (5'-(d)GTP), the precursor for synthesizing DNA or RNA in vivo, is an important raw material for various modern biotechnologies based on PCR. In this study, we investigated the application of whole-cell catalysts constructed by bacterial cell surface display in biosynthetic reactions of 5'-(d)GTP from (deoxy)guanosine-5'-monophosphate (5'-(d)GMP). By N-terminal or N- and C-terminal fusion of the ice nucleation protein, we successfully displayed the GMP kinase of Lactobacillus bulgaricus and the acetate kinase of E. coli on the surface of E. coli cells. A large amount of soluble target protein was obtained upon induction with 0.2 mM IPTG at 25 °C for 30 h. The conversion of dGMP was up to 91% when catalysed by the surface-displayed enzymes at 37 °C for 4 h. Up to 95% of the GMP was converted after 3 h of reaction. The stability of the whole-cell catalyst at 37 °C was very good. The enzyme activity was maintained above 50% after 9 rounds of recovery. Our research showed that only one-twentieth of the initial substrate concentration of added ATP was sufficient to meet the reaction requirements.

Abstract
One of the main challenges of using recombinant enzymes is that they are derived from genetically-modified microorganisms commonly located in the intracellular region. The use of these recombinant enzymes for commercial purposes requires the additional processes of cell disruption and purification, which may result in enzyme loss, denaturation, and increased total production cost. In this study, the cellulase gene of Bacillus licheniformis ATCC 14580 was cloned, over-expressed, and surface displayed in recombinant Escherichia coli using an ice-nucleation protein (INP). INP, an outer membrane-bound protein from Pseudomonas syringae, was utilized as an anchor linker, which was cloned with a foreign cellulase gene into the pET21a vector to develop a surface display system on the outer membrane of E. coli. The resulting strain successfully revealed cellulase on the host cell surface. The over-expressed INP-cellulase fusion protein was confirmed via staining assay for determining the extracellular cellulase and Western blotting method for the molecular weight (MW) of cellulase, which was estimated to be around 61.7 kDa. Cell fractionation and localization tests demonstrated that the INP-cellulase fusion protein was mostly present in the supernatant (47.5%) and outer membrane (19.4%), while the wild-type strain intracellularly retained enzymes within cytosol (>61%), indicating that the INP gene directed the cellulase expression on the bacteria cell surface. Further studies of the optimal enzyme activity were observed at 60 °C and pH 7.0, and at least 75% of maximal enzyme activity was preserved at 70 °C.

Abstract
Monomeric autotransporters have been extensively used for export of recombinant proteins to the cell surface of Gram-negative bacteria. A bottleneck in the biosynthesis of such constructs is the passage of the outer membrane, which is facilitated by the β-domain at the C terminus of an autotransporter in conjunction with the Bam complex in the outer membrane. We have evaluated eight β-domain constructs for their capacity to secrete fused proteins to the cell surface. These constructs derive from the monomeric autotransporters Hbp, IgA protease, Ag43 and EstA and the trimeric autotransporter Hia, which all were selected because they have been previously used for secretion of recombinant proteins. We fused three different protein domains to the eight β-domain constructs, being a Myc-tag, the Hbp passenger and a nanobody or VHH domain, and assessed expression, membrane insertion and surface exposure. Our results show that expression levels differed considerably between the constructs tested. The constructs that included the β-domains of Hbp and IgA protease appeared the most efficient and resulted in expression levels that were detectable on Coomassie-stained SDS-PAGE gels. The VHH domain appeared the most difficult fusion partner to export, probably due to its complex immunoglobulin-like structure with a tertiary structure stabilized by an intramolecular disulfide bond. Overall, the Hbp β-domain compared favorably in exporting the fused recombinant proteins, because it showed in every instance tested a good level of expression, stable membrane insertion and clear surface exposure.

High-vacuum optical platform for cryo-CLEM (HOPE): A new solution for non-integrated multiscale correlative light and electron microscopy. J Struct Biol 2018; 201:63-75.

Abstract
Cryo-correlative light and electron microscopy (cryo-CLEM) offers a unique way to analyze the high-resolution structural information of cryo-vitrified specimen by cryo-electron microscopy (cryo-EM) with the guide of the search for unique events by cryo-fluorescence microscopy (cryo-FM). To achieve cryo-FM, a trade-off must be made between the temperature and performance of objective lens. The temperature of specimen should be kept below devitrification while the distance between the objective lens and specimen should be short enough for high resolution imaging. Although special objective lens was designed in many current cryo-FM approaches, the unavoided frosting and ice contamination are still affecting the efficiency of cryo-CLEM. In addition, the correlation accuracy between cryo-FM and cryo-EM would be reduced during the current specimen transfer procedure. Here, we report an improved cryo-CLEM technique (high-vacuum optical platform for cryo-CLEM, HOPE) based on a high-vacuum optical stage and a commercial cryo-EM holder. The HOPE stage comprises of a special adapter to suit the cryo-EM holder and a high-vacuum chamber with an anti-contamination system. It provides a clean and enduring environment for cryo specimen, while the normal dry objective lens in room temperature can be used via the optical windows. The 'touch-free' specimen transfer via cryo-EM holder allows least specimen deformation and thus maximizes the correlation accuracy between cryo-FM and cryo-EM. Besides, we developed a software to perform semi-automatic cryo-EM acquisition of the target region localized by cryo-FM. Our work provides a new solution for cryo-CLEM and can be adapted for different commercial fluorescence microscope and electron microscope.

Abstract
BACKGROUND Bacterial surface display is an attractive technique for the production of cell-anchored, functional proteins and engineering of whole-cell catalysts. Although various outer membrane proteins have been used for surface display, an easy and versatile high-throughput-compatible assay for evaluating and developing surface display systems is missing. RESULTS Using a single domain antibody (also called nanobody) with high affinity for green fluorescent protein (GFP), we constructed a system that allows for fast, fluorescence-based detection of displayed proteins. The outer membrane hybrid protein LppOmpA and the autotransporter C-IgAP exposed the nanobody on the surface of Escherichia coli with very different efficiency. Both anchors were capable of functionally displaying the enzyme Chitinase A as a fusion with the nanobody, and this considerably increased expression levels compared to displaying the nanobody alone. We used flow cytometry to analyse display capability on single-cell versus population level and found that the signal peptide of the anchor has great effect on display efficiency. CONCLUSIONS We have developed an inexpensive and easy read-out assay for surface display using nanobody:GFP interactions. The assay is compatible with the most common fluorescence detection methods, including multi-well plate whole-cell fluorescence detection, SDS-PAGE in-gel fluorescence, microscopy and flow cytometry. We anticipate that the platform will facilitate future in-depth studies on the mechanism of protein transport to the surface of living cells, as well as the optimisation of applications in industrial biotech.
