Abstract
Sortase-mediated ligation (SML) has emerged as a powerful and versatile methodology for site-specific protein conjugation, functionalization/labeling, immobilization, and design of biohybrid molecules and systems. However, the broader application of SML faces several challenges, such as limited activity and stability, dependence on calcium ions, and reversible reactions caused by nucleophilic side-products. Over the past decade, protein engineering campaigns and particularly directed evolution, have been extensively employed to overcome sortase limitations, thereby expanding the potential application of SML in multiple directions, including therapeutics, biorthogonal chemistry, biomaterials, and biosensors. This review provides an overview of achieved advancements in sortase engineering and highlights recent progress in utilizing SML in combination with other state-of-the-art chemical and biological methodologies. The aim is to encourage scientists to employ sortases in their conjugation experiments.

Abstract
Recently, functional nanowire production using amyloids as a scaffold for protein immobilization has attracted attention. However, protein immobilization on amyloid fibrils often caused protein inactivation. In this study, we investigated protein immobilization using enzymatic peptide ligation to suppress protein inactivation during immobilization. We attempted to immobilize functional molecules such as green fluorescent protein (GFP) and Nanoluc to a transthyretin (TTR) amyloid using microbial transglutaminase (MTG), which links the glutamine side chain to the primary amine. Linkage between amyloid fibrils and functional molecules was achieved through the MTG substrate sequence, and the functional molecules-loaded nanowires were successfully fabricated. We also found that the synthetic process from amyloidization to functional molecules immobilization could be achieved in a single-step procedure.All rights reserved.

Abstract
Hydrogels have been developed for different biomedical applications such as in vitro culture platforms, drug delivery, bioprinting and tissue engineering. Enzymatic cross-linking has many advantages for its ability to form gels in situ while being injected into tissue, which facilitates minimally invasive surgery and adaptation to the shape of the defect. It is a highly biocompatible form of cross-linking, which permits the harmless encapsulation of cytokines and cells in contrast to chemically or photochemically induced cross-linking processes. The enzymatic cross-linking of synthetic and biogenic polymers also opens up their application as bioinks for engineering tissue and tumor models. This review first provides a general overview of the different cross-linking mechanisms, followed by a detailed survey of the enzymatic cross-linking mechanism applied to both natural and synthetic hydrogels. A detailed analysis of their specifications for bioprinting and tissue engineering applications is also included.

Abstract
The spread of coronavirus diseases has resulted in a clarion call to develop potent drugs and vaccines even as different strains appear beyond human prediction. An initial step that is integral to the viral entry into host cells results from an active-targeted interaction of the viral spike (S) proteins and the cell surface receptor, called angiotensin-converting enzyme 2 (ACE2). Thus, engineered ACE2 has been an interesting decoy inhibitor against emerging coronavirus infestation. This article discusses promising innovative ACE2 engineering pathways for current and emerging coronavirus therapeutic development. First, we provide a brief discussion of some ACE2-associated human coronaviruses and their cell invasion mechanism. Then, we describe and contrast the individual spike proteins and ACE2 receptor interactions, highlighting crucial hotspots across the ACE2-associated coronaviruses. Lastly, we address the importance of multivalency in ACE2 nanomedicine engineering and discuss novel approaches to develop and achieve multivalent therapeutic outcomes. Beyond coronaviruses, these approaches will serve as a paradigm to develop new and improved treatment technologies against pathogens that use ACE2 receptor for invasion.

Abstract
Protein-based conjugates have been extensively utilized in various biotechnological and therapeutic applications. In order to prepare homogeneous conjugates, site-specific modification methods and efficient purification strategies are both critical factors to be considered. The development of general and facile conjugation and purification strategies is therefore highly desirable. Here, we apply a capture and release strategy to create protein conjugates based on Designed Ankyrin Repeat Proteins (DARPins), which are engineered antigen-binding proteins with prominent affinity and selectivity. In this case, DARPins that target the epithelial cell adhesion molecule (EpCAM), a diagnostic cell surface marker for many types of cancer, were employed. The DARPins were first genetically modified with a C-terminal CVIA sequence to install an enzyme recognition site and then labeled with an aldehyde functional group employing protein farnesyltransferase. Using a capture and release strategy, conjugation of the labeled DARPins to a TAMRA fluorophore was achieved with either purified proteins or directly from crude E. coli lysate and used in subsequent flow cytometry and confocal imaging analysis. DARPin-MMAE conjugates were also prepared yielding a construct manifesting an IC50 of 1.3 nM for cell killing of EpCAM positive MCF-7 cells. The method described here is broadly applicable to enable the streamlined one-step preparation of protein-based conjugates.

Abstract
Site-specific protein modification is a widely-used biochemical tool. However, there are many challenges associated with the development of protein modification techniques, in particular, achieving site-specificity, reaction efficiency and versatility. The engineering of peptide ligases and their substrates has been used to address these challenges. This review will focus on sortase, peptidyl asparaginyl ligases (PALs) and variants of subtilisin; detailing how their inherent specificity has been utilised for site-specific protein modification. The review will explore how the engineering of these enzymes and substrates has led to increased reaction efficiency mainly due to enhanced catalytic activity and reduction of reversibility. It will also describe how engineering peptide ligases to broaden their substrate scope is opening up new opportunities to expand the biochemical toolkit, particularly through the development of techniques to conjugate multiple substrates site-specifically onto a protein using orthogonal peptide ligases. We highlight chemical and biochemical strategies taken to optimise peptide and protein modification using peptide ligases.![]()

Abstract
In the past two decades, the emergence of coronavirus diseases has been dire distress on both continental and global fronts and has resulted in the search for potent treatment strategies. One crucial challenge in this search is the recurrent mutations in the causative virus spike protein, which lead to viral escape issues. Among the current promising therapeutic discoveries is the use of nanobodies and nanobody-like molecules. While these nanobodies have demonstrated high-affinity interaction with the virus, the unpredictable spike mutations have warranted the need for avidity-inspired therapeutics of potent inhibitors such as nanobodies. This article discusses novel approaches for the design of anti-SARS-CoV-1 and -2 nanobodies to facilitate advanced innovations in treatment technologies. It further discusses molecular interactions and suggests multivalent protein nanotechnology and chemistry approaches to translate mere molecular affinity into avidity.

Abstract
Abstract Multimeric and polymeric proteins are large biomacromolecules consisting of multiple protein molecules as their monomeric units, connected through covalent or non-covalent bonds. Genetic modification and post-translational modifications (PTMs) of proteins offer alternative strategies for designing and creating multimeric and polymeric proteins. Multimeric proteins are commonly prepared by genetic modification, whereas polymeric proteins are usually created through PTMs. There are two methods that can be applied to create polymeric proteins: self-assembly and crosslinking. Self-assembly offers a spontaneous reaction without a catalyst, while the crosslinking reaction offers some catalyst options, such as chemicals and enzymes. In addition, enzymes are excellent catalysts because they provide site-specificity, rapid reaction, mild reaction conditions, and activity and functionality maintenance of protein polymers. However, only a few enzymes are applicable for the preparation of protein polymers. Most of the other enzymes are effective only for protein conjugation or labeling. Here, we review novel and applicable strategies for the preparation of multimeric proteins through genetic modification and self-assembly. We then describe the formation of protein polymers through site-selective crosslinking reactions catalyzed by enzymes, crosslinking reactions of non-natural amino acids, and protein-peptide (SpyCatcher/SpyTag) interactions. Finally, we discuss the potential applications of these protein polymers. Graphical abstract ![]()

Abstract
Enzymatic reaction offers site-specific conjugation of protein units to form protein conjugates or protein polymers with intrinsic functions. Herein, we report horseradish peroxidase (HRP)- and microbial transglutaminase (MTG)-catalyzed orthogonal conjugation reactions to create antifungal protein polymers composed of Pteris ryukyuensis chitinase-A (ChiA) and its two domains, catalytic domain, CatD, and chitin-binding domain, LysM2. We engineered the ChiA and CatD by introducing a peptide tag containing tyrosine (Y-tag) at N-termini and a peptide tag containing lysine and tyrosine (KY-tag) at C-termini to construct Y-ChiA-KY and Y-CatD-KY. Also, LysM2 with Y-tag and KY-tag (Y-LysM2-KY) or with a glutamine-containing peptide tag (Q-tag) (LysM2-Q) were constructed. The proteins with Y-tag and KY-tag were efficiently polymerized by HRP reaction through the formation of dityrosine bonds at the tyrosine residues in the peptide tags. The Y-CatD-KY polymer was further treated by MTG to orthogonally graft LysM2-Q to the KY-tag via isopeptide formation between the side chains of the glutamine and lysine residues in the peptide tags to form LysM2-grafted CatD polymer. The LysM2-grafted CatD polymer exhibited significantly higher antifungal activity than the homopolymer of Y-ChiA-KY and the random copolymer of Y-CatD-KY and Y-LysM2-KY, demonstrating that the structural differences of artificial chitinase polymers have a significant impact on the antifungal activity. This strategy of polymerization and grafting reaction of protein can contribute to the further research and development of functional protein polymers for specific applications in various fields in biotechnology.

Abstract
Sequence-specific protein ligations are widely used to produce customized proteins "on demand." Such chimeric, immobilized, fluorophore-conjugated or segmentally labeled proteins are generated using a range of chemical, (split) intein, split domain, or enzymatic methods. Where short ligation motifs and good chemoselectivity are required, ligase enzymes are often chosen, although they have a number of disadvantages, for example poor catalytic efficiency, low substrate specificity, and side reactions. Here, we describe a sequence-specific protein ligase with more favorable characteristics. This ligase, Connectase, is a monomeric homolog of 20S proteasome subunits in methanogenic archaea. In pulldown experiments with Methanosarcina mazei cell extract, we identify a physiological substrate in methyltransferase A (MtrA), a key enzyme of archaeal methanogenesis. Using microscale thermophoresis and X-ray crystallography, we show that only a short sequence of about 20 residues derived from MtrA and containing a highly conserved KDPGA motif is required for this high-affinity interaction. Finally, in quantitative activity assays, we demonstrate that this recognition tag can be repurposed to allow the ligation of two unrelated proteins. Connectase catalyzes such ligations at substantially higher rates, with higher yields, but without detectable side reactions when compared with a reference enzyme. It thus presents an attractive tool for the development of new methods, for example in the preparation of selectively labeled proteins for NMR, the covalent and geometrically defined attachment of proteins on surfaces for cryo-electron microscopy, or the generation of multispecific antibodies.

Abstract
Enzymes play a central role in the detection of target molecules in biotechnological fields. Most probes used in detection are bifunctional proteins comprising enzymes and binding proteins conjugated by chemical reactions. To create a highly sensitive detection probe, it is essential to increase the enzyme-to-binding protein ratio in the probe. However, if the chemical reactions required to prepare the probe are insufficiently site-specific, the detection probe may lose functionality. Genetic modifications and enzyme-mediated post-translational modifications (PTMs) can ensure the site-specific conjugation of proteins. They are therefore promising strategies for the production of detection probes with high enzyme contents, i.e., polymeric bifunctional proteins. Herein, we review recent advances in the preparation of bifunctional protein conjugates and polymeric bifunctional protein conjugates for detection. We have summarized research on genetically fused proteins and enzymatically prepared polymeric bifunctional proteins, and will discuss the potential use of protein polymers in various detection applications.

Abstract
Single-chain protein affinity ligands are recombinant polypeptides that recreate the antigen-binding site of parental, monoclonal antibodies (mAbs) or present unique binding surfaces derived from display technologies, computational design, or other approaches. These diverse ligands have several advantages over full-length mAbs as agents for delivery of small molecule, protein, and nanoparticle cargoes to desired sites in the body. However, they present unique challenges for modification and bioconjugation. Fusion of a LPXTGG motif, or "sortag," and a 5-amino acid, flexible linker to the C-terminus of these affinity ligands enables high-efficiency transpeptidation by the bacterial enzyme, Sortase A, and site-specific addition of fluorophores, radiolabels, or functional groups for oriented and stoichiometrically controlled bioconjugation. We describe in detail this method and address several challenges and pitfalls in the purification and characterization of modified single-chain affinity ligands.

Abstract
The structure of a protein complex needs to be controlled appropriately to maximize its functions. Herein, we report the linear polymerization of bacterial alkaline phosphatase (BAP) through the site-specific cross-linking reaction catalyzed by Trametes sp. laccase (TL). We introduced a peptide loop containing a tyrosine (Y-Loop) to BAP, and the Y-Looped BAP was treated with TL. The Y-Looped BAP formed linear polymers, whereas BAP fused with a C-terminal peptide containing a tyrosine (Y-tag) showed an irregular shape after TL treatment. The sterically confined structure of the Y-Loop could be responsible for the formation of linear BAP polymers. TL-catalyzed copolymerization of Y-Looped BAP and a Y-tagged chimeric antibody-binding protein, pG2pA-Y, resulted in the formation of linear bifunctional protein copolymers that could be employed as protein probes in an enzyme-linked immunosorbent assay (ELISA). Copolymers comprising Y-Looped BAP and pG2pA-Y at a molar ratio of 100:1 exhibited the highest signal in the ELISA with 26- and 20-fold higher than a genetically fused chimeric protein, BAP-pG2pA-Y, and its polymeric form, respectively. This result revealed that the morphology of the copolymers was the most critical feature to improve the functionality of the protein polymers as detection probes, not only for immunoassays but also for other diagnostic applications.

Abstract
S. aureus sortase A (SrtA), a calcium-dependent transpeptidase, is frequently employed to site-specifically label the C-terminus of recombinant proteins bearing an LPXTG SrtA recognition motif. Unfortunately, SrtA suffers from low turnover rates, resulting in poor ligation efficiencies even with optimized reaction conditions. In this chapter, we describe proximity-based sortase-mediated ligation (PBSL), which uses the SpyTag-SpyCatcher peptide-protein pair to link SrtA to target proteins and dramatically improves reaction rate and ligation efficiency.

Abstract
S. aureus sortase A (SrtA), a calcium-dependent bacterial transpeptidase, is commonly used to site-specifically label proteins containing a LPXTG SrtA recognition motif with a wide array of chemical moieties. A major limitation of sortase-mediated labeling, however, is SrtA's poor binding affinity to its recognition motif, resulting in long reaction times and poor ligation efficiencies. Here we describe proximity-based sortase-mediated ligation (PBSL), which utilizes the SpyTag-SpyCatcher peptide-protein pair to tether target proteins with a SrtA recognition motif to SrtA, dramatically increasing their local concentrations and overcoming this limitation.

Abstract
Protein-based conjugates are valuable constructs for a variety of applications. Conjugation of proteins to fluorophores is commonly used to study their cellular localization and the protein-protein interactions. Modification of therapeutic proteins with either polymers or cytotoxic moieties greatly enhances their pharmacokinetics or potency. To label a protein of interest, conventional direct chemical reaction with the side-chains of native amino acids often yields heterogeneously modified products. This renders their characterization complicated, requires difficult separation steps and may impact protein function. Although modification can also be achieved via the insertion of unnatural amino acids bearing bioorthogonal functional groups, these methods can have lower protein expression yields, limiting large scale production. As a site-specific modification method, enzymatic protein labelling is highly efficient and robust under mild reaction conditions. Significant progress has been made over the last five years in modifying proteins using enzymatic methods for numerous applications, including the creation of clinically relevant conjugates with polymers, cytotoxins or imaging agents, fluorescent or affinity probes to study complex protein interaction networks, and protein-linked materials for biosensing. This review summarizes developments in enzymatic protein labelling over the last five years for a panel of ten enzymes, including sortase A, subtiligase, microbial transglutaminase, farnesyltransferase, N-myristoyltransferase, phosphopantetheinyl transferases, tubulin tyrosin ligase, lipoic acid ligase, biotin ligase and formylglycine generating enzyme.

Abstract
Molecular biologists and chemists alike have long sought to modify proteins with substituents that cannot be installed by standard or even advanced genetic approaches. We here describe the use of transpeptidases to achieve these goals. Living systems encode a variety of transpeptidases and peptide ligases that allow for the enzyme-catalyzed formation of peptide bonds, and protein engineers have used directed evolution to enhance these enzymes for biological applications. We focus primarily on the transpeptidase sortase A, which has become popular over the past few years for its ability to perform a remarkably wide variety of protein modifications, both in vitro and in living cells.

Abstract
Proteins play a major role in biosensors in which they provide catalytic activity and specificity in molecular recognition. However, the immobilization process is far from straightforward as it often affects the protein functionality. Extensive interaction of the protein with the surface or significant surface crowding can lead to changes in the mobility and conformation of the protein structure. This review will provide insights as to how an analysis of the physico-chemical features of the protein surface before the immobilization process can help to identify the optimal immobilization approach. Such an analysis can help to preserve the functionality of the protein when on a biosensor surface.

Abstract
The conjugation of antibodies to drugs and drug carriers improves delivery to target tissues. Widespread implementation and effective translation of this pharmacologic strategy awaits the development of affinity ligands capable of a defined degree of modification and highly efficient bioconjugation without loss of affinity. To date, such ligands are lacking for the targeting of therapeutics to vascular endothelial cells. To enable site-specific, click-chemistry conjugation to therapeutic cargo, we used the bacterial transpeptidase, sortase A, to attach short azidolysine containing peptides to three endothelial-specific single chain antibody fragments (scFv). While direct fusion of a recognition motif (sortag) to the scFv C-terminus generally resulted in low levels of sortase-mediated modification, improved reaction efficiency was observed for one protein, in which two amino acids had been introduced during cloning. This prompted insertion of a short, semi-rigid linker between scFv and sortag. The linker significantly enhanced modification of all three proteins, to the extent that unmodified scFv could no longer be detected. As proof of principle, purified, azide-modified scFv was conjugated to the antioxidant enzyme, catalase, resulting in robust endothelial targeting of functional cargo in vitro and in vivo.

Abstract
We produced a functional polymer whose framework comprised transthyretin (TTR) amyloid fibrils. In order to immobilize functional molecules onto the amyloid fibrils, transpeptidase sortase A (srtA), which catalyzes the covalent binding of LPXTG with polyglycine, was employed. After the preparation of the amyloid fibril of LPETGG-tagged TTR, immobilization of Gly5-fused GFP on the amyloid fibrils by srtA-mediated transpeptidation was carried out. SrtA recognized the amyloid fibrils consisting of an LPETGG-tagged TTR variant (L55P) as a good substrate, resulting in successful preparation of a GFP-immobilized amyloid. Intriguingly, the replacement of GFP with Gly5-fused luciferase was confirmed when the GFP-immobilized amyloids were mixed with Gly5-luciferase in the presence of srtA. Thus, it was found that functional molecules covalently immobilized on amyloid could be detached and substituted with other tagged molecules by using srtA.

Abstract
Protein bioconjugation has been a crucial tool for studying biological processes and developing therapeutics. Sortase A (SrtA), a bacterial transpeptidase, has become widely used for its ability to site-specifically label proteins with diverse functional moieties, but a significant limitation is its poor reaction kinetics. In this work, we address this by developing proximity-based sortase-mediated ligation (PBSL), which improves the ligation efficiency to over 95 % by linking the target protein to SrtA using the SpyTag-SpyCatcher peptide-protein pair. By expressing the target protein with SpyTag C-terminal to the SrtA recognition motif, it can be covalently captured by an immobilized SpyCatcher-SrtA fusion protein during purification. Following the ligation reaction, SpyTag is cleaved off, rendering PBSL traceless, and only the labeled protein is released, simplifying target protein purification and labeling to a single step.

Abstract
Functional nanoparticles are valuable materials for energy production, bioelectronics, and diagnostic devices. The combination of biomolecules with nanosized material produces a new hybrid material with properties that can exceed the ones of the single components. Hematite is a widely available material that has found application in various sectors such as in sensing and solar energy production. We report a single-step immobilization process based on affinity and achieved by genetically engineering the protein of interest to carry a hematite-binding peptide. Fabricated hematite nanoparticles were then investigated for the immobilization of the two biomolecules C-phycocyanin (CPC) and laccase from Bacillus pumilus (LACC) under mild conditions. Genetic engineering of biomolecules with a hematite-affinity peptide led to a higher extent of protein immobilization and enhanced the catalytic activity of the enzyme.

Abstract
The transpeptidation reaction catalyzed by bacterial sortases continues to see increasing use in the construction of novel protein derivatives. In addition to growth in the number of applications that rely on sortase, this field has also seen methodology improvements that enhance reaction performance and scope. In this opinion, we present an overview of key developments in the practice and implementation of sortase-based strategies, including applications relevant to structural biology. Topics include the use of engineered sortases to increase reaction rates, the use of redesigned acyl donors and acceptors to mitigate reaction reversibility, and strategies for expanding the range of substrates that are compatible with a sortase-based approach.

Abstract
Antibody labelling to reporter molecules is gaining popularity due to its many potential applications for diagnostics and therapeutics. However, non-directional bioconjugation methods which are commonly used often results in the loss of target binding capabilities. Therefore, a site-specific enzymatic based bioconjugation such as sortase-mediated transpeptidation allows for a more rapid and efficient method of antibody conjugation for diagnostic applications. Here we describe the utilization of sortase A bioconjugation to conjugate a single chain fragment variable (scFv) to the extracellular invertase (invB) from Zymomonas mobilis with the aim of developing an invertase based immunoassay. In addition, conjugation to enhanced green fluorescent protein (eGFP) was also validated to show the flexibility of the method. The invertase conjugated complex was successfully applied for the detection of antibody-antigen interaction using a personal glucose meter (PGM) for assay readout. The setup was used in both a direct and competitive assay highlighting the robustness of the conjugate for assay development. The method provides an alternative conjugation process to allow easy exchange of antibodies to facilitate rapid development of diagnostic assays for various diseases on the PGM platform.

Abstract
Bacteria possess complex and varying cell walls with many surface exposed proteins. Sortases are responsible for the covalent attachment of specific proteins to the peptidoglycan of the cell wall of Gram-positive bacteria. Sortase A of Staphylococcus aureus, which is seen as the archetypal sortase, has been shown to be essential for pathogenesis and has therefore received much attention as a potential target for novel therapeutics. Being widely present in Gram-positive bacteria, it is likely that other Gram-positive pathogens also require sortases for their pathogenesis. Sortases have also been shown to be of significant use in a range of industrial applications. We review current knowledge of the sortase family in terms of their structures, functions and mechanisms and summarize work towards their use as antibacterial targets and microbiological tools.

Abstract
Adenosine-5'-triphosphate-dependent enzyme catalysed reactions are widespread in nature. Consequently, the enzymes involved have an intrinsic potential for use in syntheses of high value products. Although regeneration systems for ATP starting from adenosine-5'-diphosphate are available, certain limitations exist for both in vitro and in vivo applications requiring ATP regeneration from adenosine-5'-monophosphate, or adenosine. Following a short overview of the chemical and thermodynamic background, this Minireview focuses on emerging enzymes and methodologies for ATP regeneration. A large range of as yet unexploited reactions will be accessible with new, powerful, multistep ATP regeneration systems that use cheap phosphate donors and provide high longevity, compatibility, and robustness under process conditions. Their potential might go far beyond the direct use of ATP in enzymatic reactions; enzyme discovery, and engineering, as well as immobilisation strategies, will help to realise such systems.
