Abstract
Glycoprotein therapeutics are currently used by large patient populations and generate significant revenue for the biopharmaceutical industry. These therapeutic proteins are currently purified at industrial scale using individualized processes involving multiple chromatographic steps. In the absence of a viable affinity platform method, the required chromatographic steps are difficult to develop and inevitably lead to significant yield losses. Further, during preclinical development, there is a need for reliable platform technologies capable of performing high-throughput screening for biologic candidates. Although affinity tags can provide a solution to some of these challenges, they require specific affinity resins, and the tag itself can interfere with the target protein characteristics. Fusion protein systems consisting of elastin-like polypeptide (ELP) and self-cleaving split inteins such as Npu DnaE can serve as potential non-chromatographic platform technologies for the single-step purification of tagless glycoproteins expressed in mammalian cells. In this chapter, we demonstrate the use of this technology to obtain highly purified anti-ErbB2 ML39 single-chain variable fragment (scFv) expressed from Expi293F suspension cells.

Abstract
Angiotensin-converting enzyme I (ACE) is a key part of the renin-angiotensin system. Its main function is to regulate blood pressure and the balance of salts in the body. Somatic ACE has two domains, N-C-, each of which has a catalytic site that exhibits 60%sequence identity. The N-domain has a specific action in the hydrolysis of beta-amyloid bodies and angiotensin (1-7), which activates the MAS receptor and triggers anti-thrombotic and anti-inflammatory actions. Our goal was to obtain the catalytic site Ala361 to Gly468 of the N domain region, csACEN, without needing purification by chromatography. We employed a method that uses an Elastin-like Polypeptide (ELP) and Intein sequences linked to the peptide of interest. The more differential for obtaining the pure peptide was the cultivation temperatures in the synthesis of ELPcsACEN at 37 °C, with a significant increase in expression. In the purification by ELP precipitation, we recorded the highest efficiency in the concentrations of 0.57 M and 0.8 M of ammonium sulfate buffer. Intein autocleavage study allows removal of the ELP sequence at acidic pH, with the buffers MES and Tris-HCl The present study defined the best conditions for obtaining pure csACEN that the literature has not yet described for peptides. Obtaining pure csACEN aims at future studies for therapeutic use in hypertension, Alzheimer's, and oncology.

Abstract
This research focuses on the construction of an affinity purification system based on Cfa DnaE split intein. Cfa DnaE intein is an artificially constructed intein with the advantages of a fast cleavage reaction and good stability. In a previous study, a purification system that uses Cfa intein as a tag was constructed, the separation of the target protein and the tag during the purification process was completed, and the purity of the purified target protein reached 98.21%. Guided by molecular docking results, we identified flexible regions in the split intein and inserted several glycines into the protein to decrease the stability of the Cfa IC , thereby improving the regenerability of the IN media. Inserting 6 glycines between amino acids 14 and 15 of IC improved the regeneration rate of IC -GFP on the column to approximately 96%.

Abstract
Protein splicing is a self-catalyzed event where the intervening sequence intein cleaves off, joining the flanking exteins together to generate a functional protein. Attempts have been made to regulate the splicing rate through variations in temperature, pH, and metals. Although metal-regulated protein splicing has been more captivating to researchers, metals were shown to only inhibit splicing reactions that confine their application. This is the first study to show the effect of nanoparticles (NPs) on protein splicing. We found that gold nanoparticles (AuNPs) of various sizes can increase the splicing efficiency by more than 50% and the N-terminal cleavage efficiency by more than 45% in Mycobacterium tuberculosis SufB precursor protein. This study provides an effective strategy for engineering splicing-enhanced intein platforms. UV-vis absorption spectroscopy, isothermal titration calorimetry (ITC), and transmission electron microscopy (TEM) confirmed AuNP interaction with the native protein. Quantum mechanics/molecular mechanics (QM/MM) analysis suggested a significant reduction in the energy barrier at the N-terminal cleavage site in the presence of gold atom, strengthening our experimental evidence on heightened the N-terminal cleavage reaction. The encouraging observation of enhanced N-terminal cleavage and splicing reaction can have potential implementations from developing a rapid drug delivery system to designing a contemporary protein purification system.

Abstract
The phase separation of biomolecules has become the focus of intense research in the past decade, with a growing body of research implicating this phenomenon in essentially all biological functions, including but not limited to homeostasis, stress responses, gene regulation, cell differentiation, and disease. Excellent reviews have been published previously on the underlying physical basis of liquid-liquid phase separation (LLPS) of biological molecules (Nat. Phys. 2015, 11, 899-904) and LLPS as it occurs natively in physiology and disease (Science 2017, 357, eaaf4382; Biochemistry 2018, 57, 2479-2487; Chem. Rev. 2014, 114, 6844-6879). Here, we review how the theoretical physical basis of LLPS has been used to better understand the behavior of biomolecules that undergo LLPS in natural systems and how this understanding has also led to the development of novel synthetic systems that exhibit biomolecular phase separation, and technologies that exploit these phenomena. In part 1 of this Review, we explore the theory behind the phase separation of biomolecules and synthetic macromolecules and introduce a few notable phase-separating biomolecules. In part 2, we cover experimental and computational methods used to study phase-separating proteins and how these techniques have uncovered the mechanisms underlying phase separation in physiology and disease. Finally, in part 3, we cover the development and applications of engineered phase-separating polypeptides, ranging from control of their self-assembly to create defined supramolecular architectures to reprogramming biological processes using engineered IDPs that exhibit LLPS.

Abstract
We evaluated several intein-based self-cleaving affinity tags for expression and single-step affinity chromatography purification of recombinant proteins produced in Escherichia coli. We used human growth hormone (hGH) as target protein that contains two internal disulfide bridges and an N-terminal phenylalanine. Use of N-terminal thiol-induced Sce VMA1 intein affinity tag resulted in purified hGH deficient in disulfide bonds. Inteins with self-cleavage inducible by pH and/or temperature shift were analyzed. N-terminal Ssp DnaX intein affinity tag resulted in a completely cleaved cytosolic protein, whereas N-terminal Ssp DnaB intein affinity tag resulted in a cytosolic fusion protein incapable of releasing hGH. Periplasmic expression of target protein was analyzed using an N-terminal signal peptide and C-terminal Ssp DnaX pH-inducible self-cleaving affinity tag. The fusion protein was properly expressed in pH 8 buffered culture medium. Fusion of a periplasmic signal peptide to the N-terminus of the POI allowed secretion to the periplasmic region and presence of the natural N-terminal amino acid of the POI following cleavage. Periplasmic expression of hGH fused to this novel C-terminal DnaX intein-based self-cleaving affinity tag made possible expression and purification of hGH protein containing disulfide bonds and free of extra amino acids.

Abstract
BACKGROUND RNA trans-splicing joins exons from different pre-mRNA transcripts to generate a chimeric product. Trans-splicing can also occur at the protein level, with split inteins mediating the ligation of separate gene products to generate a mature protein. SOURCES OF DATA Comprehensive literature search of published research papers and reviews using Pubmed. AREAS OF AGREEMENT Trans-splicing techniques have been used to target a wide range of diseases in both in vitro and in vivo models, resulting in RNA, protein and functional correction. AREAS OF CONTROVERSY Off-target effects can lead to therapeutically undesirable consequences. In vivo efficacy is typically low, and delivery issues remain a challenge. GROWING POINTS Trans-splicing provides a promising avenue for developing novel therapeutic approaches. However, much more research needs to be done before developing towards preclinical studies. AREAS TIMELY FOR DEVELOPING RESEARCH Increasing trans-splicing efficacy and specificity by rational design, screening and competitive inhibition of endogenous cis-splicing.

Abstract
The microbial transglutaminase (mTGase) from Streptomyces mobaraense is widely used in the food industry. However, recombinant production of mTGase is challenging because the mTGase is synthesized as an inactive zymogen, and needs to be activated by proteolytic processing. In this study, self-cleaving intein Ssp DnaB was applied to activate the mTGase in Corynebacterium glutamicum. Premature cleavage of intein Ssp DnaB also occurred, but instead of suppressing premature cleavage, this phenomenon was used to produce active mTGase in C. glutamicum. Both SDS-PAGE analysis and mTGase activity assays indicated that the premature cleavage of intein Ssp DnaB activated the mTGase intracellularly in C. glutamicum. The subsequent N-terminal amino acid sequencing and site-directed mutagenesis studies further showed that the premature cleavage activated the mTGase intracellularly, in a highly specific manner. Moreover, the growth performance of C. glutamicum was not noticeably affected by the intracellular expression of active mTGase. Finally, the mTGase was produced in a 2 L bioreactor, with activity up to 49 U/mL, the highest intracellular mTGase activity ever reported. Using premature cleavage of intein Ssp DnaB to activate mTGase in C. glutamicum, we produced high levels of intracellular active mTGase. Moreover, this approach did not require any further processing steps, such as protease treatment or lengthy incubation, greatly simplifying the production of active mTGase. This efficient and simple approach has great potential for the large-scale industrial production of active mTGase.

Abstract
A purification system was constructed with the N-segment of the Npu DnaE split intein as an affinity ligand immobilized onto an epoxy-activated medium and the C-segment used as the cleavable tag fusing target protein. The affinity properties of C-tagged proteins adsorbed on IN affinity chromatography medium were studied with GFP as a model target protein. The saturated adsorption capacity and dynamic adsorption capacity reached 51.9-21.0 mg mL-1, respectively. With this system, two model proteins, GFP and alcohol dehydrogenase (ADH), has been successfully taglessly purified with regulation of Zn2+ and DTT. The yield, purification factor and purity of purified tagless GFP reached 39, 11.7 and 97%, respectively; while these values for purified tagless ADH were 38.2, 6.8 and 91%, respectively. These results showed that the system for Npu DnaE split intein-mediated affinity adsorption and in situ cleavage is a potential platform for recombinant protein production.

Abstract
The N-terminal cleavage of fusion tags to restore the native N-terminus of recombinant proteins is a challenging task and up to today, protocols need to be optimized for different proteins individually. Within this work, we present a novel protease that was designed in-silico to yield enhanced promiscuity toward different N-terminal amino acids. Two mutations in the active-site amino acids of human Caspase-2 were determined to increase the recognition of branched amino-acids, which show only poor binding capabilities in the unmutated protease. These mutations were determined by sequential and structural comparisons of Caspase-2 and Caspase-3 and their effect was additionally predicted using free-energy calculations. The two mutants proposed in the in-silico studies were expressed and in-vitro experiments confirmed the simulation results. Both mutants showed not only enhanced activities toward branched amino acids, but also smaller, unbranched amino acids. We believe that the created mutants constitute an important step toward generalized procedures to restore original N-termini of recombinant fusion proteins.

Abstract
Intervening proteins (Inteins) are identified as protein domains in a precursor protein structure. Inteins can excise itself from precursor protein and join the remaining portions which result in forming an active protein. In this study, the transcript expression level of recombinant human Interferon beta (rhIFNβ) connected to the self-cleavage Intein-ELK16 (LELELKLKLELELKLK) tag was measured by real-time PCR in HEK293T cell line. First, the sequence of Mycobacterium tuberculosis RecA (Mtu recA) was obtained from the InBase database to do appropriate changes including adding the restriction sites, kozak sequence, signal peptide and ELK16 sequence by SnapGene software. The RNA secondary structure were also examined using the online RNA Fold 2.2 web server. Next, the construct was inserted into pUC19 plasmid. The sequence of rhIFNβ was also cloned into pBudCE4.1 vector. In the next step, the rhIFNβ was ligated into the construct (self-cleavage tag of ELK16) using T4 DNA ligase and the recombinant construct was transfected into HEK293T cell line. Finally, expression of the cassette was evaluated by real-time PCR. The analysis of secondary RNA structure indicates a minimum free energy of MEF - 261.10 kcal/mol. Our results indicate that IFNβ was upregulated (37.8-fold, p < 0.0001) in cells which transfected by rhIFNβ-ELK16 compared to the mock and un-transfected conditions. Altogether, our results show that the presence of mini self-cleavage Intein-ELK16 tag along with the rhIFNβ had no interference in transcription of rhIFNβ in the HEK293T cell line.

Abstract
Protein splicing domains, also called inteins, have become a powerful biotechnological tool for applications involving molecular biology and protein engineering. Early applications of inteins focused on self-cleaving affinity tags, generation of recombinant polypeptide α-thioesters for the production of semisynthetic proteins and backbone cyclized polypeptides. The discovery of naturallyoccurring split-inteins has allowed the development of novel approaches for the selective modification of proteins both in vitro and in vivo. This review gives a general introduction to protein splicing with a focus on their role in expanding the applications of intein-based technologies in protein engineering and chemical biology.

BIOTECHNOLOGY FOR BIOFUELS 2019; 12:157.

Abstract
BACKGROUND In the enzymatic conversion of biomass, it becomes an important issue to efficiently and cost-effectively degrade cellulose into fermentable glucose. β-Glucosidase (Bgluc), an essential member of cellulases, plays a critical role in cellulosic biomass degradation. The difficulty in improving the stability of Bgluc has been a bottleneck in the enzyme-dependent cellulose degradation. The traditional method of protein purification, however, leads to higher production cost and a decrease in activity. To simplify and efficiently purify Bgluc with modified special properties, Bgluc-tagged ELP and His with defined phase transitions was designed to facilitate the process. RESULTS Here, a novel binary ELP and His tag was fused with Bgluc from termite Coptotermes formosanus to construct a Bgluc-linker-ELP-His recombinant fusion protein (BglucLEH). The recombinant plasmid Bgluc expressing a His tag (BglucH) was also constructed. The BglucLEH and BglucH were expressed in E. coli BL21 and purified using inverse transition cycling (ITC) or Ni-NTA resin. The optimum salt concentration for the ITC purification of BglucLEH was 0.5 M (NH4)2SO4 and the specific activity of BglucLEH purified by ITC was 75.5 U/mg for substrate p-NPG, which was slightly higher than that of BglucLEH purified by Ni-NTA (68.2 U/mg). The recovery rate and purification fold of BglucLEH purified by ITC and Ni-NTA were 77.8%, 79.1% and 12.60, 11.60, respectively. The results indicated that purification with ITC was superior to the traditional Ni-NTA. The K m of BglucLEH and BglucH for p-NPG was 5.27 and 5.73 mM, respectively. The K ca t/K m (14.79 S-1 mM-1) of BglucLEH was higher than that of BglucH (12.10 S-1 mM-1). The effects of ELP tag on the enzyme activity, secondary structure and protein stability were also studied. The results showed that ELP tag did not affect the secondary structure or enzyme activity of Bgluc. More importantly, ELP improved the protein stability in harsh conditions such as heating and exposure to denaturant. CONCLUSION The Bgluc-linker-ELP-His system shows wide application prospect in maintaining the activity, efficient purification and improving the stability of Bgluc. These properties of BglucLEH make it an interesting tool to reduce cost, to improve the efficiency of biocatalyst and potentially to enhance the degradation of lignocellulosic biomass.

Abstract
Although many protein fusion tags have been developed for recombinant protein production to improve protein yields or facilitate purification, determining the expression and purification of the fusion protein still remain to be a time-consuming and laborious procedure. In this work, we designed a histidine-rich elastin-like polypeptide (HRELP) fusion tag and found that it could be efficiently expressed in E. coli cells and specifically stained with Pauly's reagent in a couple of minutes post SDS-PAGE analysis. Moreover, in Pauly's reagent-stained polyacrylamide gels, only the bands of HRELP fusion proteins were yellow and could be clearly visualized with little background. Furthermore, both HRELPs and HRELP20-BMP2 fusion protein could be purified by a method of pH shift-mediated inverse transition cycling (ITC). In our opinion, the HRELP established in this study may be considered as a multifunctional protein tag which could make its fusion proteins being quickly detected by Pauly staining and simply purified by pH-triggered ITC in addition to having the potential to sustained release its fusion proteins.

Abstract
Npu DnaE is a naturally occurred split intein possessing robust trans-splicing activity and could be engineered to perform rapid C-terminal cleavage module by a single mutation D118G. Unfortunately, however, for this modified selfcleaving module, reducing agents were needed to trigger the rapid cleavage, which prevents the utilization in purification of disulfide bonds containing recombinant proteins. In this study, we demonstrated that the unpaired cysteine residues in Npu DnaE tend to form disulfide bonds, and contributed to the reduction of the cleavage under non-reducing conditions. This redox trap can be disrupted by site-directed mutation of these unpaired cysteines. The results further indicated that the position 28 and 59 may play certain roles in the correct folding of the active conformation.

Abstract
We have constructed novel plasmids pANY2, pANY3, and pANY6 for flexible cloning with low false positives, efficient expression, and convenient purification of proteins. The pANY2 plasmid can be used for efficient isopropyl-β-d-thiogalactoside (IPTG) induced protein expression, while the pANY3 plasmid can be used for temperature-induced expression. The pANY6 plasmid contains a self-cleaving elastin-like protein (ELP) tag for purification of recombinant protein by simple ELP-mediated precipitation steps and removal of the ELP tag by self-cleavage. A urea-based denaturation and refolding processes for renaturation of insoluble inclusion bodies can be conveniently integrated into the ELP-mediated precipitation protocol, removing time-consuming dialysis steps. These novel vectors, together with the described strategies of gene cloning, protein expression, and purification, may have wide applications in biosciences, agricultural, food technologies, and so forth.

Abstract
Conventional column chromatography processes to purify recombinant proteins are associated with high production costs and slow volumetric throughput at both laboratory and large scale. Non-chromatographic purifications based on selective aggregating tags have the potential to reduce costs with acceptable protein yields. A significant drawback, however, is that current proteolytic approaches for post-purification tag removal after are expensive and non-scalable. To address this problem, we have developed two non-chromatographic purification strategies that use either the elastin-like polypeptide (ELP) tag or the β-roll tag (BRT17) in combination with an engineered split intein for tag removal. The use of the split intein eliminates premature cleavage during expression and provides controlled cleavage under mild conditions after purification. These self-cleaving aggregating tags were used to efficiently purify β-lactamase (β-lac), super-folder green fluorescent protein (sfGFP), streptokinase (SK) and maltose binding protein (MBP), resulting in increased yields compared to previous ELP and BRT17-based methods. Observed yields of purified targets for both systems typically ranged from approximately 200 to 300 micrograms per milliliter of cell culture, while overall recoveries ranged from 10 to 85 percent and were highly dependent on the target protein.

Abstract
Fusions of elastin-like peptide (ELP) purification tags and self-cleaving inteins provide a powerful platform for purifying tagless recombinant proteins without the need for conventional packed-bed columns. A drawback to this method has been premature cleaving of the ELP tag during expression, before the purification procedure can take place. Here we demonstrate a split-intein method, where the self-cleaving intein is divided into two inactive segments during expression and purification. Spontaneous assembly of the purified intein segments then restores self-cleaving activity to deliver the tagless target protein.

Abstract
Protein purification remains a central need for biotechnology. In recent years, a class of aggregating tags has emerged, which offers a quick, cost-effective and column-free alternative for producing recombinant proteins (and also peptides) with yield and purity comparable to that of the popular His-tag. These column-free tags induce the formation of aggregates (during or after expression) when fused to a target protein or peptide, and upon separation from soluble impurities, the target protein or peptide is subsequently released via a cleavage site. In this review, we categorize these tags as follows: (i) tags that induce inactive protein aggregates in vivo; (ii) tags that induce active protein aggregates in vivo; and (iii) tags that induce soluble expression in vivo, but aggregates in vitro. The respective advantages and disadvantages of these tags are discussed, and compared to the three conventional tags (His-tag, maltose-binding protein [MBP] tag, and intein-mediated purification with a chitin-binding tag [IMPACT-CN]). While this new class of aggregating tags is promising, more systematic tests are required to further the use. It is conceivable, however, that the combination of these tags and the more traditional columns may significantly reduce the costs for resins and columns, particularly for the industrial scale.

Abstract
For half a century aqueous two-phase systems (ATPSs) have been applied for the extraction and purification of biomolecules. In spite of their simplicity, selectivity, and relatively low cost they have not been significantly employed for industrial scale bioprocessing. Recently their ability to be readily scaled and interface easily in single-use, flexible biomanufacturing has led to industrial re-evaluation of ATPSs. The purpose of this review is to perform a SWOT analysis that includes a discussion of: (i) strengths of ATPS partitioning as an effective and simple platform for biomolecule purification; (ii) weaknesses of ATPS partitioning in regard to intrinsic problems and possible solutions; (iii) opportunities related to biotechnological challenges that ATPS partitioning may solve; and (iv) threats related to alternative techniques that may compete with ATPS in performance, economic benefits, scale up and reliability. This approach provides insight into the current status of ATPS as a bioprocessing technique and it can be concluded that most of the perceived weakness towards industrial implementation have now been largely overcome, thus paving the way for opportunities in fermentation feed clarification, integration in multi-stage operations and in single-step purification processes.

Abstract
The discovery of inteins in the early 1990s opened the door to a wide variety of new technologies. Early engineered inteins from various sources allowed the development of self-cleaving affinity tags and new methods for joining protein segments through expressed protein ligation. Some applications were developed around native and engineered split inteins, which allow protein segments expressed separately to be spliced together in vitro. More recently, these early applications have been expanded and optimized through the discovery of highly efficient trans-splicing and trans-cleaving inteins. These new inteins have enabled a wide variety of applications in metabolic engineering, protein labeling, biomaterials construction, protein cyclization, and protein purification.

Abstract
The purification of recombinant proteins by affinity chromatography is one of the most efficient strategies due to the high recovery yields and purity achieved. However, this is dependent on the availability of specific affinity adsorbents for each particular target protein. The diversity of proteins to be purified augments the complexity and number of specific affinity adsorbents needed, and therefore generic platforms for the purification of recombinant proteins are appealing strategies. This justifies why genetically encoded affinity tags became so popular for recombinant protein purification, as these systems only require specific ligands for the capture of the fusion protein through a pre-defined affinity tag tail. There is a wide range of available affinity pairs "tag-ligand" combining biological or structural affinity ligands with the respective binding tags. This review gives a general overview of the well-established "tag-ligand" systems available for fusion protein purification and also explores current unconventional strategies under development.
