Abstract
Multienzyme systems are essential for utilizing di-, oligo-, and polysaccharides as fuels in enzymatic fuel cells effectively. However, the transfer of electrons generated by one enzymatic reaction in a multienzyme cascade at the electrode may be impeded by other enzymes, potentially hindering the overall efficiency. In this study, carbon paper was first modified by incorporating single-walled carbon nanotubes (SWCNTs) and gold nanoparticles (AuNPs) sequentially. Subsequently, glucose oxidase (GOx) and a trehalase-gelatin mixture were immobilized separately on the nanostructured carbon paper via layer-by-layer adsorption to mitigate the electron transfer hindrance caused by trehalase. The anode was first fabricated by immobilizing GOx and trehalase on the modified carbon paper, and the cathode was then fabricated by immobilizing bilirubin oxidase on the nanostructured electrode. The SWCNTs and AuNPs were distributed adequately on the electrode surface, which improved the electrode performance, as demonstrated by electrochemical and morphological analyses. An enzymatic fuel cell was assembled and tested using trehalose as the fuel, and a maximum power density of 23 μW cm-2 was obtained at a discharge current density of 60 μA cm-2. The anode exhibited remarkable reusability and stability.

Abstract
The phloem is a highly specialized vascular tissue that forms a fundamentally important transport and signaling pathway in plants. It is therefore a system worth protecting. The main function of the phloem is to transport the products of photosynthesis throughout the whole plant, but it also transports soluble signaling molecules and propagates electrophysiological signals. The phloem is constantly threatened by mechanical injuries, phloem-sucking pests and parasites, and the spread of pathogens, which has led to the evolution of efficient defense mechanisms. One such mechanism involves structural phloem proteins, which are thought to facilitate sieve element occlusion following injury and to defend the plant against pathogens. In leguminous plants, specialized structural phloem proteins known as forisomes form unique mechanoproteins via sophisticated molecular interaction and assembly mechanisms, thus enabling reversible sieve element occlusion. By understanding the structure and function of forisomes and other structural phloem proteins, we can develop a toolbox for biotechnological applications in material science and medicine. Furthermore, understanding the involvement of structural phloem proteins in plant defense mechanisms will allow phloem engineering as a new strategy for the development of crop varieties that are resistant to pests, pathogens and parasites.

Abstract
Enzyme immobilization is an essential technology for commercializing biocatalysis. It imparts stability, recoverability, and other valuable features that improve the effectiveness of biocatalysts. While many avenues to join an enzyme to solid phases exist, protein-mediated immobilization is rapidly developing and has many advantages. Protein-mediated immobilization allows for the binding interaction to be genetically coded, can be used to create artificial multienzyme cascades, and enables modular designs that expand the variety of enzymes immobilized. By designing around binding interactions between protein domains, they can be integrated into functional materials for protein immobilization. These materials are framed within the context of biocatalytic performance, immobilization efficiency, and stability of the materials. In this review, supports composed entirely of protein are discussed first, with systems such as cellulosomes and protein cages being discussed alongside newer technologies like spore-based biocatalysts and forizymes. Protein-composite materials such as polymersomes and protein-inorganic supraparticles are then discussed to demonstrate how protein-mediated strategies are applied to many classes of solid materials. Critical analysis and future directions of protein-based immobilization are then discussed, with a particular focus on both computational and design strategies to advance this area of research and make it more broadly applicable to many classes of enzymes.

The functionality of plant mechanoproteins (forisomes) is dependent on the dual role of conserved cysteine residues. Int J Biol Macromol 2021; 193:1332-1339.

Abstract
Forisomes are giant polyprotein complexes that undergo reversible conformational rearrangements from a spindle-like to a plug-like state in response to Ca2+ or changes in pH. They act as valves in the plant vasculature, and reproduce this function in vitro to regulate flow in microfluidic capillaries controlled by electro-titration. Heterologous expression in yeast or plants allows the large-scale production of tailor-made artificial forisomes for technical applications. Here we investigated the unexpected disintegration of artificial forisomes in response to Ca2+ following the deletion of the M1 motif in the MtSEO-F1 protein or the replacement of all four conserved cysteine residues therein. This phenomenon could be mimicked in wild-type forisomes under reducing conditions by adding a thiol alkylating agent. We propose a model in which reversible changes in forisome structure depend on cysteine residues with ambiguous redox states, allowing the formation of intermolecular disulfide bridges (confirmed by mass spectrometry) as well as noncovalent thiol interactions to connect forisome substructures in the dispersed state. This is facilitated by the projection of the M1 motif from the MtSEO-F1 protein as part of an extended loop. Our findings support the rational engineering of disintegrating forisomes to control the release of peptides or enzymes in microfluidic systems.

Abstract
Forisomes are giant self-assembling mechanoproteins that undergo reversible structural changes in response to Ca2+ and various other stimuli. Artificial forisomes assembled from the monomer MtSEO-F1 can be used as smart biomaterials, but the molecular basis of their functionality is not understood. To determine the role of protein polymerization in forisome activity, we tested the Ca2+ association of MtSEO-F1 dimers (the basic polymerization unit) by circular dichroism spectroscopy and microscale thermophoresis. We found that soluble MtSEO-F1 dimers neither associate with Ca2+ nor undergo structural changes. However, polarization modulation infrared reflection absorption spectroscopy revealed that aggregated MtSEO-F1 dimers and fully-assembled forisomes associate with Ca2+ , allowing the hydration of poorly-hydrated protein areas. A change in the signal profile of complete forisomes indicated that Ca2+ interacts with negatively-charged regions in the protein complexes that only become available during aggregation. We conclude that aggregation is required to establish the Ca2+ response of forisome polymers.

Abstract
The synthesis of complex molecules using multiple enzymes simultaneously in one reaction vessel has rapidly emerged as a new frontier in the field of bioprocess technology. However, operating different enzymes together in a single vessel limits their operational performance which needs to be addressed. With this respect, scaffolding proteins play an immense role in bringing different enzymes together in a specific manner. The scaffolding improves the catalytic performance, enzyme stability and provides an optimal micro-environment for biochemical reactions. This review describes the components of protein scaffolds, different ways of constructing a protein scaffold-based multi-enzyme complex, and their effects on enzyme kinetics. Moreover, different conjugation strategies viz; dockerin-cohesin interaction, SpyTag-SpyCatcher system, peptide linker-based ligation, affibody, and sortase-mediated ligation are discussed in detail. Various analytical and characterization tools that have enabled the development of these scaffolding strategies are also reviewed. Such mega-enzyme complexes promise wider applications in the field of biotechnology and bioengineering.

Abstract
In a biological system, the spatiotemporal arrangement of enzymes in a dense cellular milieu, subcellular compartments, membrane-associated enzyme complexes on cell surfaces, scaffold-organized proteins, protein clusters, and modular enzymes have presented many paradigms for possible multienzyme immobilization designs that were adapted artificially. In metabolic channeling, the catalytic sites of participating enzymes are close enough to channelize the transient compound, creating a high local concentration of the metabolite and minimizing the interference of a competing pathway for the same precursor. Over the years, these phenomena had motivated researchers to make their immobilization approach naturally realistic by generating multienzyme fusion, cluster formation via affinity domain-ligand binding, cross-linking, conjugation on/in the biomolecular scaffold of the protein and nucleic acids, and self-assembly of amphiphilic molecules. This review begins with the discussion of substrate channeling strategies and recent empirical efforts to build it synthetically. After that, an elaborate discussion covering prevalent concepts related to the enhancement of immobilized enzymes' catalytic performance is presented. Further, the central part of the review summarizes the progress in nature motivated multienzyme assembly over the past decade. In this section, special attention has been rendered by classifying the nature-inspired strategies into three main categories: (i) multienzyme/domain complex mimic (scaffold-free), (ii) immobilization on the biomolecular scaffold, and (iii) compartmentalization. In particular, a detailed overview is correlated to the natural counterpart with advances made in the field. We have then discussed the beneficial account of coassembly of multienzymes and provided a synopsis of the essential parameters in the rational coimmobilization design.

Abstract
Keto acids are essential organic acids that are widely applied in pharmaceuticals, cosmetics, food, beverages, and feed additives as well as chemical synthesis. Currently, most keto acids on the market are prepared via chemical synthesis. The biochemical synthesis of keto acids has been discovered with the development of metabolic engineering and applied toward the production of specific keto acids from renewable carbohydrates using different metabolic engineering strategies in microbes. In this review, we provide a systematic summary of the types and applications of keto acids, and then summarize and compare the chemical and biochemical synthesis routes used for the production of typical keto acids, including pyruvic acid, oxaloacetic acid, α-oxobutanoic acid, acetoacetic acid, ketoglutaric acid, levulinic acid, 5-aminolevulinic acid, α-ketoisovaleric acid, α-keto-γ-methylthiobutyric acid, α-ketoisocaproic acid, 2-keto-L-gulonic acid, 2-keto-D-gluconic acid, 5-keto-D-gluconic acid, and phenylpyruvic acid. We also describe the current challenges for the industrial-scale production of keto acids and further strategies used to accelerate the green production of keto acids via biochemical routes.

Abstract
Forisomes are large mechanoprotein complexes found solely in legumes such as Medicago truncatula. They comprise several "sieve element occlusion by forisome" (SEO-F) subunits, with MtSEO-F1 as the major structure-forming component. SEO-F proteins possess three conserved domains -an N-terminal domain (SEO-NTD), a potential thioredoxin fold, and a C-terminal domain (SEO-CTD)- but structural and biochemical data are scarce and little is known about the contribution of these domains to forisome assembly. To identify key amino acids involved in MtSEO-F1 dimerization and complex formation, we investigated protein-protein interactions by bimolecular fluorescence complementation and the analysis of yeast two-hybrid and random mutagenesis libraries. We identified a SEO-NTD core region as the major dimerization site, with abundant hydrophobic residues and rare charged residues suggesting dimerization is driven by the hydrophobic effect. We also found that ~45% of the full-length MtSEO-F1 sequence must be conserved for higher-order protein assembly, indicating that large interaction surfaces facilitate stable interactions, contributing to the high resilience of forisome bodies. Interestingly, the removal of 62 amino acids from the C-terminus did not disrupt forisome assembly. This is the first study unraveling interaction sites and mechanisms within the MtSEO-F1 protein at the level of dimerization and complex formation.

Abstract
Precisely organized enzyme complexes are often found in nature to support complex metabolic reactions in a highly efficient and specific manner. Scaffolding enzymes on artificial materials has thus gained attention as a promising biomimetic strategy to design biocatalytic systems with enhanced productivity. Herein, a versatile scaffolding platform that can immobilize enzymes on customizable nanofibers is reported. An ultrastable self-assembling filamentous protein, the gamma-prefoldin (γ-PFD), is genetically engineered to display an array of peptide tags, which can specifically and stably bind enzymes containing the counterpart domain through simple in vitro mixing. Successful immobilization of proteins along the filamentous template in tunable density is first verified using fluorescent proteins. Then, two different model enzymes, glucose oxidase and horseradish peroxidase, are used to demonstrate that scaffold attachment could enhance the intrinsic catalytic activity of the immobilized enzymes. Considering the previously reported ability of γ-PFD to bind and stabilize a broad range of proteins, the filament's interaction with the bound enzymes may have created a favorable microenvironment for catalysis. It is envisioned that the strategy described here may provide a generally applicable methodology for the scaffolded assembly of multienzymatic complexes for use in biocatalysis.

Abstract
In this study, lanthanum-containing mesoporous MCM-41 (La-MCM-41) with different amount of lanthanum were synthesized and were used for colorimetric detection of glucose. As prepared La-MCM-41 were characterized by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). The quantitative amounts of incorporated lanthanum into MCM-41 structure were estimated by energy dispersive X-ray spectrometry. The prepared La-MCM-41 provided high intrinsic peroxidase-like activity in the presence of peroxidise 3,3',5,5'-tetramethylbenzidine (TMB) and H2O2 for accurate determination of glucose. This process produced a blue color in aqueous solution that directly relates to H2O2 concentration. The effect of different parameters such as the content of incorporated lanthanum, pH, temperature and time of reaction on the peroxidase-like activity was studied. The colorimetric detection of H2O2 was led to a linear dynamic range from 50 to 1000 μM (r2 = 0.9988) and low detection limit of 37.5 μM for glucose in aqueous solution. These results are comparable (close to) or better than some previous reports. Thus, La-MCM-41 can be used as admirable alternative design for colorimetric sensing of glucose.

Abstract
In nature, enzymatic reaction cascades, i.e., realized in metabolic networks, operate with unprecedented efficacy, with the reactions often being spatially and temporally orchestrated. The principle of "learning from nature" has in recent years inspired the setup of synthetic reaction cascades combining biocatalytic reaction steps to artificial cascades. Hereby, the spatial organization of multiple enzymes, e.g., by coimmobilization, remains a challenging task, as currently no generic principles are available that work for every enzyme. We here present a tunable, genetically programmed coimmobilization strategy that relies on the fusion of a coiled-coil domain as aggregation inducing-tag, resulting in the formation of catalytically active inclusion body coimmobilizates (Co-CatIBs). Coexpression and coimmobilization was proven using two fluorescent proteins, and the strategy was subsequently extended to two enzymes, which enabled the realization of an integrated enzymatic two-step cascade for the production of (1 R,2 R)-1-phenylpropane-1,2-diol (PPD), a precursor of the calicum channel blocker diltiazem. In particular, the easy production and preparation of Co-CatIBs, readily yielding a biologically produced enzyme immobilizate renders the here presented strategy an interesting alternative to existing cascade immobilization techniques.

Abstract
Background The self-assembly of cellulosomes on the surface of yeast is a promising strategy for consolidated bioprocessing to convert cellulose into ethanol in one step. Results In this study, we developed a novel synthetic cellulosome that anchors to the endogenous yeast cell wall protein a-agglutinin through disulfide bonds. A synthetic scaffoldin ScafAGA3 was constructed using the repeated N-terminus of Aga1p and displayed on the yeast cell surface. Secreted cellulases were then fused with Aga2p to assemble the cellulosome. The display efficiency of the synthetic scaffoldin and the assembly efficiency of each enzyme were much higher than those of the most frequently constructed cellulosome using scaffoldin ScafCipA3 from Clostridium thermocellum. A complex cellulosome with two scaffoldins was also constructed using interactions between the displayed anchoring scaffoldin ScafAGA3 and scaffoldin I ScafCipA3 through disulfide bonds, and the assembly of secreted cellulases to ScafCipA3. The newly designed cellulosomes enabled yeast to directly ferment cellulose into ethanol. Conclusions This is the first report on the development of complex multiple-component assembly system through disulfide bonds. This strategy could facilitate the construction of yeast cell factories to express synergistic enzymes for use in biotechnology.
