Driscoll CL, Keeble AH, Howarth MR. SpyMask enables combinatorial assembly of bispecific binders. Nat Commun 2024; 15:2403.

Abstract
Bispecific antibodies are a successful and expanding therapeutic class. Standard approaches to generate bispecifics are complicated by the need for disulfide reduction/oxidation or specialized formats. Here we present SpyMask, a modular approach to bispecifics using SpyTag/SpyCatcher spontaneous amidation. Two SpyTag-fused antigen-binding modules can be precisely conjugated onto DoubleCatcher, a tandem SpyCatcher where the second SpyCatcher is protease-activatable. We engineer a panel of structurally-distinct DoubleCatchers, from which binders project in different directions. We establish a generalized methodology for one-pot assembly and purification of bispecifics in 96-well plates. A panel of binders recognizing different HER2 epitopes were coupled to DoubleCatcher, revealing unexpected combinations with anti-proliferative or pro-proliferative activity on HER2-addicted cancer cells. Bispecific activity depended sensitively on both binder orientation and DoubleCatcher scaffold geometry. These findings support the need for straightforward assembly in different formats. SpyMask provides a scalable tool to discover synergy in bispecific activity, through modulating receptor organization and geometry.

Abstract
Manipulating protein architectures beyond genetic control has attracted widespread attention. Catcher/Tag systems enable highly specific conjugation of proteins in vivo and in vitro via an isopeptide-bond. They provide efficient, robust, and irreversible strategies for protein conjugation and are simple yet powerful tools for a variety of applications in enzyme industry, vaccines, biomaterials, and cellular applications. Here we summarize recent development of the Catcher/Tag toolbox with a particular emphasis on the design of Catcher/Tag pairs targeted for specific applications. We cover the current limitations of the Catcher/Tag systems and discuss the pH sensitivity of the reactions. Finally, we conclude some of the future directions in the development of this versatile protein conjugation method and envision that improved control over inducing the ligation reaction will further broaden the range of applications.

Abstract
Covalent bonds and noncovalent interactions play crucial roles in enzyme self-assembly. Here, we designed a Tag/Catcher system named NGTag/NGCatcher in which the Catcher is a highly charged protein that can bind proteins with positively charged tails and rapidly form a stable isopeptide bond with NGTag. In this study, we present a multienzyme strategy based on covalent bonds and noncovalent interactions. In vitro, mCherry, YFP, and GFP can form protein-rich three-dimensional networks based on NGCatcher, NGTag, and RK (Arginine/Lysine) tails, respectively. Furthermore, this technology was applied to improve lycopene production in Escherichia coli. Three key enzymes were involved in lycopene production variants from Deinococcus wulumuqiensis R12 of NGCatcher_CrtE, NGTag_Idi, and RKIspARK, where the multienzyme complexes were clearly observed in vivo and in vitro, and the lycopene production in vivo was 17.8-fold higher than that in the control group. The NGTag/NGCatcher system will provide new opportunities for in vivo and in vitro multienzyme catalysis.

Abstract
Proteins can be empowered via SpyTag for anchoring and nanoassembly, through covalent bonding to SpyCatcher partners. Here we generate a switchable version of SpyCatcher, allowing gentle purification of SpyTagged proteins. We introduce numerous histidines adjacent to SpyTag’s binding site, giving moderate pH-dependent release. After phage-based selection, our final SpySwitch allows purification of SpyTag- and SpyTag003-fusions from bacterial or mammalian culture by capture at neutral pH and release at pH 5, with purity far beyond His-tag methods. SpySwitch is also thermosensitive, capturing at 4 °C and releasing at 37 °C. With flexible choice of eluent, SpySwitch-purified proteins can directly assemble onto multimeric scaffolds. 60-mer multimerization enhances immunogenicity and we use SpySwitch to purify receptor-binding domains from SARS-CoV-2 and 11 other sarbecoviruses. For these receptor-binding domains we determine thermal resilience (for mosaic vaccine development) and cross-recognition by antibodies. Antibody EY6A reacts across all tested sarbecoviruses, towards potential application against new coronavirus pandemic threats. The SpyCatcher-SpyTag system allows protein anchoring and nanoassembly. Here, the authors engineer SpySwitch, a dually switchable Catcher which allows gentle purification of SpyTagged proteins prior to downstream applications such as the assembly of virus-like particles.

Abstract
Recently a technique based on the interaction between adhesion proteins extracted from Streptococcus pyogenes, known as SpyRing, has been widely used to improve the thermal resilience of enzymes, the assembly of biostructures, cancer cell recognition and other fields. It was believed that the covalent cyclization of protein skeleton caused by SpyRing reduces the conformational entropy of biological structure and improves its rigidity, thus improving the thermal resilience of the target enzyme. However, the effects of SpyTag/ SpyCatcher interaction with this enzyme are poorly understood, and their regulation of enzyme properties remains unclear. Here, for simplicity, we took the single domain enzyme lichenase from Bacillus subtilis 168 as an example, studied the interface interactions in the SpyRing by molecular dynamics simulations, and examined the effects of the changes of electrostatic interaction and van der Waals interaction on the thermal resilience of target enzyme. The simulations showed that the interface between SpyTag/SpyCatcher and the target enzyme is different from that found by geometric matching method and highlighted key mutations at the interface that might have effect on the thermal resilience of the enzyme. Our calculations highlighted interfacial interactions between enzyme and SpyTag/SpyCatcher, which might be useful in rational designs of the SpyRing.

Abstract
The bacterial extracellular matrix forms autonomously, giving rise to complex material properties and multicellular behaviors. Synthetic matrix analogues can replicate these functions but require exogenously added material or have limited programmability. Here, we design a two-strain bacterial system that self-synthesizes and structures a synthetic extracellular matrix of proteins. We engineered Caulobacter crescentus to secrete an extracellular matrix protein composed of an elastin-like polypeptide (ELP) hydrogel fused to supercharged SpyCatcher [SC(-)]. This biopolymer was secreted at levels of 60 mg/liter, an unprecedented level of biomaterial secretion by a native type I secretion apparatus. The ELP domain was swapped with either a cross-linkable variant of ELP or a resilin-like polypeptide, demonstrating this system is flexible. The SC(-)-ELP matrix protein bound specifically and covalently to the cell surface of a C. crescentus strain that displays a high-density array of SpyTag (ST) peptides via its engineered surface layer. Our work develops protein design guidelines for type I secretion in C. crescentus and demonstrates the autonomous secretion and assembly of programmable extracellular protein matrices, offering a path forward toward the formation of cohesive engineered living materials.IMPORTANCE Engineered living materials (ELM) aim to mimic characteristics of natural occurring systems, bringing the benefits of self-healing, synthesis, autonomous assembly, and responsiveness to traditional materials. Previous research has shown the potential of replicating the bacterial extracellular matrix (ECM) to mimic biofilms. However, these efforts require energy-intensive processing or have limited tunability. We propose a bacterially synthesized system that manipulates the protein content of the ECM, allowing for programmable interactions and autonomous material formation. To achieve this, we engineered a two-strain system to secrete a synthetic extracellular protein matrix (sEPM). This work is a step toward understanding the necessary parameters to engineering living cells to autonomously construct ELMs.

Abstract
The interplay between protein folding and chemical reaction has been an intriguing subject. In this contribution, we report the study of SpyTag and SpyCatcher reactive mutants using a combination of sodium dodecyl sulfate-polyacrylamide gel electrophoresis, liquid chromatography and mass spectrometry, circular dichroism, and NMR spectroscopy. It was found that the wild-type SpyCatcher is well-folded in solution and docks with SpyTag to form an intermediate that promotes isopeptide bond formation. By contrast, the double mutant SpyCatcherVA is disordered in solution yet remains reactive toward SpyTag, forming a well-folded covalent complex. Control experiments using the catalytically inactive mutants further reveal the critical role of the isopeptide bond in stabilizing the otherwise loose SpyTag-SpyCatcherVA complex, amplifying the effect of the minute sequence disparity. We believe that the synergy between protein folding and isopeptide bonding is an effective way to enhance protein stability and engineer protein-protein interactions.

Abstract
The E2 envelope protein is the main protective antigen of classical swine fever virus (CSFV). Importantly, gram-positive enhancer matrix (GEM) particles can work as an immunostimulant and/or carrier system to improve the immune effect of antigens. In this study, the artificially designed E2-Spy was expressed and glycosylated in Pichia pastoris, and subsequently conjugated with SpyCatcher-PA which was expressed in Escherichia coli. The conjugated E2-Spy-PA was displayed on the surface of GEM particles, generating the E2-Spy-PA-GEM complex. Blocking ELISA analysis and neutralization assays showed that both E2-Spy and E2-Spy-PA-GEM complexes induced high levels of anti-CSFV antibodies in mice. Furthermore, statistical analyses indicated that the E2-Spy-PA-GEM complex exhibited enhanced immunogenicity compared with E2-Spy alone.

Abstract
Precaution of classical swine fever (CSF) is an important mission for the worldwide swine industry. Glycoprotein E2 is the leading antigen candidate for subunit vaccine of classical swine fever virus (CSFV). In this study, two Spy-tagged E2 genes were synthesized in vitro and subcloned into pMCO-AOX vector for intracellular expression in Pichia pastoris after methanol induction. Western blot analysis and semi-quantitative analysis showed that the yield of recombinant E2 protein was improved 17.87 folds by using co-translocational signal peptide cSIG. After the construction of the tandem multiple copy expression vectors, further increase of E2 production was observed by repetitive transforming expression vectors into P. pastoris genome. Finally, the yeast transformants harboring 8 or 16 copies of cSIG-E2-Spy increased the E2 expression level by 27.01-fold or 30.72-fold, respectively. These results demonstrate that utilizing co-translocational signal peptide together with multi-copy integration strategy can increase the production of recombinant E2 protein efficiently.

Abstract
Herein, we report an intrinsically disordered protein SpyStapler that can catalyze the isopeptide bond formation between two peptide tags, that is, SpyTag and BDTag, both in vitro and in vivo. SpyStapler and BDTag are developed by splitting SpyCatcher-the cognate protein partner of SpyTag-at the more solvent exposed second loop region. Regardless of their locations in protein constructs, SpyStapler enables efficient covalent coupling of SpyTag and BDTag under a variety of mild conditions in vitro (yield ∼80%). Co-expression of SpyStapler with telechelic dihydrofolate reductase (DHFR) bearing a SpyTag at N-terminus and a BDTag at C-terminus leads to direct cellular synthesis of a circular DHFR. Mechanistic studies involving circular dichroism and nuclear magnetic resonance spectrometry reveal that SpyStapler alone is disordered in solution and forms a stable folded structure ( Tm ∼ 55 °C) in the presence of both SpyTag and BDTag upon isopeptide bonding. No ordered structure can be formed in the absence of either tag. The catalytically inactive SpyStapler-EQ mutant cannot form a stable physical complex with SpyTag and BDTag, but it can fold into ordered structure in the presence of the ligated product (SpyTag-BDTag). It suggests that the isopeptide bond is important in stabilizing the complex. Given its efficiency, resilience, and robustness, SpyStapler provides new opportunities for bioconjugation and creation of complex protein architectures.

Abstract
Vaccines based on virus-like particles (VLPs) can induce potent B cell responses. Some non-chimeric VLP-based vaccines are highly successful licensed products (e.g., hepatitis B surface antigen VLPs as a hepatitis B virus vaccine). Chimeric VLPs are designed to take advantage of the VLP framework by decorating the VLP with a different antigen. Despite decades of effort, there have been few licensed chimeric VLP vaccines. Classic approaches to create chimeric VLPs are either genetic fusion or chemical conjugation, using cross-linkers from lysine on the VLP to cysteine on the antigen. We describe the principles that make these classic approaches challenging, in particular for complex, full-length antigens bearing multiple post-translational modifications. We then review recent advances in conjugation approaches for protein-based non-enveloped VLPs or nanoparticles, to overcome such challenges. This includes the use of strong non-covalent assembly methods (stick), unnatural amino acids for bio-orthogonal chemistry (click), and spontaneous isopeptide bond formation by SpyTag/SpyCatcher (glue). Existing applications of these methods are outlined and we critically consider the key practical issues, with particular insight on Tag/Catcher plug-and-display decoration. Finally, we highlight the potential for modular particle decoration to accelerate vaccine generation and prepare for pandemic threats in human and veterinary realms.

Abstract
Genetically encoded covalent peptide tagging technology, such as the SpyTag-SpyCatcher reaction, has emerged as a unique way to do chemistry with proteins. Herein, we report the reactivity engineering of SpyTag-SpyCatcher mutant pairs and show that distinct reactivity can be encrypted for the same reaction based on protein sequences of high similarity. Valuable features, including high selectivity, inverse temperature dependence and (nearly) orthogonal reactivity, could be achieved based on as few as three mutations. This demonstrates the robustness of the SpyTag-SpyCatcher reaction and the plasticity of its sequence specificity, pointing to a family of engineered protein chemistry tools.
