Abstract
Heterologous expression of L-asparaginase (L-ASNase) has become an important area of research due to its clinical and food industry applications. This review provides a comprehensive overview of the molecular and metabolic strategies that can be used to optimize the expression of L-ASNase in heterologous systems. This article describes various approaches that have been employed to increase enzyme production, including the use of molecular tools, strain engineering, and in silico optimization. The review article highlights the critical role that rational design plays in achieving successful heterologous expression and underscores the challenges of large-scale production of L-ASNase, such as inadequate protein folding and the metabolic burden on host cells. Improved gene expression is shown to be achievable through the optimization of codon usage, synthetic promoters, transcription and translation regulation, and host strain improvement, among others. Additionally, this review provides a deep understanding of the enzymatic properties of L-ASNase and how this knowledge has been employed to enhance its properties and production. Finally, future trends in L-ASNase production, including the integration of CRISPR and machine learning tools are discussed. This work serves as a valuable resource for researchers looking to design effective heterologous expression systems for L-ASNase production as well as for enzymes production in general.

Abstract
L-asparaginase (EC 3.5.1.1) is one of the most demanded enzymes used in the pharmaceutical industry as a drug and in the food industry to prevent the formation of toxic acrylamide. Researchers aimed to improve specific activity and reduce side effects to create safer and more potent enzyme products. However, protein modifications and heterologous expression remain problematic in the production of asparaginases from different species. Heterologous expression in optimized producer strains is rationally organized; therefore, modified and heterologous protein expression is enhanced, which is the main strategy in the production of asparaginase. This strategy solves several problems: incorrect protein folding, metabolic load on the producer strain and codon misreading, which affects translation and final protein domains, leading to a decrease in catalytic activity. The main approaches developed to improve the heterologous expression of L-asparaginases are considered in this paper.

Kudhair BK, Green J. Overproduction and purification of Mycobacterium tuberculosis WhiB3 in Escherichia coli is enhanced by co-expression with trigger factor chaperone. Protein Expr Purif 2023; 202:106197. [PMID: 36332747 DOI: 10.1016/j.pep.2022.106197] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2022] [Revised: 10/22/2022] [Accepted: 10/25/2022] [Indexed: 11/06/2022]
Abstract
Members of the WhiB-like (Wbl) family of proteins are found in Acintomycetes and are somewhat recalcitrant to overproduction as soluble proteins in the laboratory protein expression workhorse Esherichia coli. The aim of this study was to evaluate the effects of culture conditions and co-expression of the chaperone protein, trigger factor (TF), on the soluble production of recombinant Mycobacterium tuberculosis (Mtb) WhiB3. A pET28a derived expression plasmid coding for His6-WhiB3 was created and the effects of varying the concentration of inducer (IPTG), the timing of induction, the nature of the inducer (auto-induction medium) and the temperature of the cultivation on the production of soluble His6-WhiB3 were tested. Whilst His6-WhiB3 protein was readily detected, the overwhelming majority of the protein was present in the insoluble fraction of cell-free extracts. However, co-expression of the tig from pTf16, coding for TF, increased His6-WhiB3 solubility dramatically, facilitating its isolation by affinity chromatography. Purified His6-WhiB3 was shown to be monomeric, and UV-visible spectra suggested that ∼10% of the isolated protein possessed a [4Fe-4S] cluster. The secondary structural properties of His6-WhiB3 were altered by acquisition of an iron-sulfur cluster. By developing a protocol to readily overproduce and purify WhiB3, this study paves the way for future structure-function experiments.

Co-expressing GroEL-GroES, Ssa1-Sis1 and Bip-PDI chaperones for enhanced intracellular production and partial-wall breaking improved stability of porcine growth hormone. Microb Cell Fact 2020; 19:35.

Abstract
Porcine growth hormone (pGH) is a class of peptide hormones secreted from the pituitary gland, which can significantly improve growth and feed utilization of pigs. However, it is unstable and volatile in vitro. It needs to be encapsulated in liposomes when feeding livestock, whose high cost greatly limits its application in pig industry. Therefore we attempted to express pGH as intracellular soluble protein in Pichia pastoris and feed these yeasts with partial wall-breaking for swine, which could release directly pGH in intestine tract in case of being degraded in intestinal tract with low cost. In order to improve the intracellular soluble expression of pGH protein in Pichia pastoris and stability in vitro, we optimized the pGH gene, and screened molecular chaperones from E. coli and Pichia pastoris respectively for co-expressing with pGH. In addition, we had also explored conditions of mechanical crushing and fermentation. The results showed that the expression of intracellular soluble pGH protein was significantly increased after gene optimized and co-expressed with Ssa1-Sis1 chaperone from Pichia pastoris. Meanwhile, the optimal conditions of partial wall-breaking and fermentation of Pichia pastoris were confirmed, the data showed that the intracellular expression of the optimized pGH protein co-expressed with Ssa1-Sis1 could reach 340 mg/L with optimal conditions of partial wall-breaking and fermentation. Animal experiments verified that the optimized pGH protein co-expression with Ssa1-Sis1 had the best promoting effects on the growth of piglets. Our study demonstrated that Ssa1-Sis1 could enhance the intracellular soluble expression of pGH protein in Pichia pastoris and that partial wall-breaking of yeast could prevent pGH from degradation in vitro, release targetedly in the intestine and play its biological function effectively. Our study could provide a new idea to cut the cost effectively, establishing a theoretical basis for the clinic application of unstable substances in vitro.

Abstract
In a previous study, we found that rabbit anti-Toxoplasma gondii serum was capable of recognizing truncated T. gondii microneme protein 16 (TgMIC16), indicating that TgMIC16 is an essential antigenic T. gondii protein. However, the broad application of this recombinant protein is limited by its low expression level. In this study, we performed codon optimization of TgMIC16 by changing the codon-adaptation index from 0.22 to 1.0 without altering the amino acid sequence and expressed the optimized gene in three different Escherichia coli strains, followed by comparison of soluble recombinant-protein expression and yield. Our results showed that the recombinant protein rTgMIC16 was expressed as inclusion bodies in all three strains following optimization of induction parameters, and western blot analysis revealed the presence of a ~72-kD recombinant protein as a specific band following purification. A shuffle-expression strain was selected to amplify incubation products and induce expression, resulting in an overall rTgMIC16 yield of ~20 mg/L. These findings provide a basis for further investigation of TgMIC16 to elucidate its functions and interaction partners.
