Abstract
Fluorescent polymeric hydrogels are promising soft and wet media for information storage that are desirable for lifelike biomaterials and flexible electronics. Hydrogels based on engineered proteins have attracted considerable interest. However, their potential utility as information storage media has remained largely unexplored. Here, we report a protein-based hydrogel that can serve as an information storage medium. Using LOVTRAP, which consists of protein LOV2 and its binding partner ZDark1, we developed a novel strategy to decorate/release fluorescent proteins onto/from a blank protein hydrogel slate in light-controlled and spatially defined fashions, reversibly generating fluorescent patterns such as quick response codes. To increase the information storage capacity, we further developed grayscale patterning to generate pseudo-colored multi-dimensional fluorescent images. Results of this new method demonstrate a novel reversible information storage approach in soft and wet materials and open a new avenue toward developing next-generation protein-based smart materials for information storage and anti-counterfeit applications.

Abstract
Protein-based hydrogels can mimic many aspects of native extracellular matrices (ECMs) and are promising biomedical materials that find various applications in cell proliferation, drug/cell delivery, and tissue engineering. To be adapted for different tasks, it is important that the mechanical and/or biochemical properties of protein-based hydrogels can be regulated by external stimuli. Light as a regulation stimulus is of advantage because it can be easily applied in demanded spatiotemporal manners. The noncovalent binding between the light-oxygen-voltage-sensing domain 2 (LOV2) and its binding partner ZDark1 (zdk1), named as LOVTRAP, is a light-responsive interaction. The binding affinity of LOVTRAP is much higher in dark than that under blue light irradiation. Taking advantage of these light-responsive interactions, herein we endeavored to use LOVTRAP as a crosslinking mechanism to engineer light-responsive protein hydrogels. Using LOV2-containing and zdk1-containing multifunctional protein building blocks, we successfully engineered a light-responsive protein hydrogel whose viscoelastic properties can change in response to light: in the dark, the hydrogel showed higher storage modulus; under blue light irradiation, the storage modulus decreased. Due to the noncovalent nature of the LOVTRAP, the engineered LOVTRAP protein hydrogels displayed shear-thinning and self-healing properties and served as an excellent injectable protein hydrogel. We anticipated that this new class of light-responsive protein hydrogels will broaden the scope of dynamic protein hydrogels and help develop other light-responsive protein hydrogels for biomedical applications.

Abstract
Hydrogels constructed from folded protein domains are of increasing interest as resilient and responsive biomaterials, but their optimization for applications requires time-consuming and costly molecular design. Here, we explore a complementary approach to control their properties by examining the influence of crosslinking rate on the structure and viscoelastic response of a model hydrogel constructed from photochemically crosslinked bovine serum albumin (BSA). Gelation is observed to follow a heterogeneous nucleation pathway in which BSA monomers crosslink into compact nuclei that grow into fractal percolated networks. Both the viscoelastic response probed by shear rheology and the nanostructure probed by small-angle X-ray scattering (SAXS) are shown to depend on the photochemical crosslinking reaction rate, with increased reaction rates corresponding to higher viscoelastic moduli, lower fractal dimension, and higher fractal cluster size. Reaction rate-dependent changes are shown to be consistent with a transition between diffusion- and rate-limited assembly, and the corresponding changes to viscoelastic response are proposed to arise from the presence of nonfractal depletion regions, as confirmed by SAXS. This controllable nanostructure and viscoelasticity constitute a potential route for the precise control of hydrogel properties, without the need for molecular modification.

Abstract
Proteins are versatile macromolecules that can perform a variety of functions. In the past three decades, they have been commonly used as building blocks to generate a range of biomaterials. Owing to their flexibility, proteins can either be used alone or in combination with other functional molecules. Advances in synthetic and chemical biology have enabled new protein fusions as well as the integration of new functional groups leading to biomaterials with emergent properties. This review discusses protein-engineered materials from the perspectives of domain-based designs as well as physical and chemical approaches for crosslinked materials, with special emphasis on the creation of hydrogels. Engineered proteins that organize or template metal ions, bear noncanonical amino acids (NCAAs), and their potential applications, are also reviewed.

Abstract
Breaking away from the linear structure of previously reported peptide-based gelators, this study reports the first example of gel formation based on the use of cyclic peptides made of alternating d- and l-amino acids, known to self-assemble in solution to form long nanotubes. Herein, a library of cyclic peptides was systemically studied for their gelation properties in various solvents, uncovering key parameters driving both organogel and hydrogel formation. The hierarchical nature of the self-assembly process in water was characterised by a combination of electron microscopy imaging and small-angle X-ray scattering, revealing a porous network of entangled nanofibres composed by the aggregation of several cyclic peptide nanotubes. Rheology measurements then confirmed the formation of soft hydrogels.

Abstract
The design of protein-based hydrogels that include biological activity independent of structural functionality is desirable for many bioengineering applications. Here a general route for construction of protein-based hydrogel is proposed by pretreatment of protein with thiolation agent and succeeding conjugation with 4-arm PEG-acrylate via Michael addition reaction. Different swelling behaviors responding to temperature and ions are comparatively studied for hydrogel cross-linked with hemoglobin (multimeric protein), albumin (monomeric protein), and dithiothreitol (DTT, small molecule). Meanwhile, the microscopic structure change is studied to correlate with the macroscopic hydrogel swelling behavior. Results show that proteins, which function as multisite cross-linkers, affect the gel swelling behaviors, and the effect is more profound for multimeric proteins when exposed to stimulus for protein dissociation. Moreover, the catalytic activity derived from hemoglobin is also preserved in the hydrogel, as demonstrated by the successfully synthesis of the colored product. By taking advantage of each particular protein, a broad range of functional materials can be expected for potential biomedical applications, such as stimuli-responsive hydrogel and immobilized enzyme.

Abstract
Alcohol dehydrogenase D (AdhD) is a monomeric thermostable alcohol dehydrogenase from the aldo-keto reductase (AKR) superfamily of proteins. We have been exploring various strategies of engineering the activity of AdhD so that it could be employed in future biotechnology applications. Driven by insights made in other AKRs, we have made mutations in the cofactor-binding pocket of the enzyme and broadened its cofactor specificity. A pre-steady state kinetic analysis yielded new insights into the conformational behavior of this enzyme. The most active mutant enzyme concomitantly gained activity with a non-native cofactor, nicotinamide mononucleotide, NMN(H), and an enzymatic biofuel cell was demonstrated with this enzyme/cofactor pair. Substrate specificity was altered by grafting loop regions near the active site pocket from a mesostable human aldose reductase (hAR) onto the thermostable AdhD. These moves not only transferred the substrate specificity of hAR but also the cofactor specificity of hAR. We have added alpha-helical appendages to AdhD to enable it to self-assemble into a thermostable catalytic proteinaceous hydrogel. As our understanding of the structure/function relationship in AdhD and other AKRs advances, this ubiquitous protein scaffold could be engineered for a variety of catalytic activities that will be useful for many future applications.

Abstract
The development of 3D structures exploring the properties of nano-materials and biological molecules has been shown through the years as an effective path forward for the design of advanced bio-nano architectures for enzymatic fuel cells, photo-bio energy harvesting devices, nano-biosensors and bio-actuators and other bio-nano-interfacial architectures. In this study we demonstrate a scaffold design utilizing carbon nanotubes, deoxyribose nucleic acid (DNA) and a specific DNA binding transcription factor that allows for directed immobilization of a single enzyme. Functionalized carbon nanotubes were covalently bonded to a diazonium salt modified gold surface through carbodiimide chemistry creating a brush-type nanotube alignment. The aligned nanotubes created a highly ordered structure with high surface area that allowed for the attachment of a protein assembly through a designed DNA scaffold. The enzyme immobilization was controlled by a zinc finger (ZNF) protein domain that binds to a specific dsDNA sequence. ZNF 268 was genetically fused to the small laccase (SLAC) from Streptomyces coelicolor, an enzyme belonging to the family of multi-copper oxidases, and used to demonstrate the applicability of the developed approach. Analytical techniques such as X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM), and enzymatic activity analysis, allowed characterization at each stage of development of the bio-nano architecture. This article is part of a Special Issue entitled Biodesign for Bioenergetics--the design and engineering of electronic transfer cofactors, proteins and protein networks, edited by Ronald L. Koder and J.L. Ross Anderson.

Abstract
Vitreoretinal surgery has advanced in numerous directions during recent years. The removal of the vitreous body is one of the main characteristics of this surgical procedure. Several molecules have been tested in the past to fill the vitreous cavity and to mimic its functions. We here review the currently available vitreous substitutes, focusing on their molecular properties and functions, together with their adverse effects. Afterwards we describe the characteristics of the ideal vitreous substitute. The challenges facing every ophthalmology researcher are to reach a long-term intraocular permanence of vitreous substitute with total inertness of the molecule injected and the control of inflammatory reactions. We report new polymers with gelification characteristics and smart hydrogels representing the future of vitreoretinal surgery. Finally, we describe the current studies on vitreous regeneration and cell cultures to create new intraocular gels with optimal biocompatibility and rheological properties.

Abstract
Shear-thinning hydrogels are useful in numerous applications, including as injectable carriers that act as scaffolds to support cell and drug therapies. Here, we describe the engineering of a self-assembling Dock-and-Lock (DnL) system that forms injectable shear-thinning hydrogels using molecular recognition interactions that also possess photo-triggerable secondary crosslinks. These DnL hydrogels are fabricated from peptide-modified hyaluronic acid (HA) and polypeptide precursors, can self-heal immediately after shear induced flow, are cytocompatible, and can be stabilized through light-initiated radical polymerization of methacrylate functional groups to tune gel mechanics and erosion kinetics. Secondary crosslinked hydrogels retain self-adhesive properties and exhibit cooperative physical and chemical crosslinks with moduli as high as ∼10 times larger than moduli of gels based on physical crosslinking alone. The extent of reaction and change in properties are dependent on whether the methacrylate is incorporated either at the terminus of the peptide or directly to the HA backbone. Additionally, the gel erosion can be monitored through an incorporated fluorophore and physical-chemical gels remain intact in solution over months, whereas physical gels that are not covalently crosslinked erode completely within days. Mesenchymal stem cells exhibit increased viability when cultured in physical- chemical gels, compared with those cultured in gels based on physical crosslinks alone. The physical properties of these DnL gels may be additionally tuned by adjusting component compositions, which allows DnL gels with a wide range of physical properties to be constructed for use.

Abstract
We have created a set of rationally designed peptides that form calcium-dependent hydrogels based on the beta roll peptide domain. In the absence of calcium, the beta roll domain is intrinsically disordered. Upon the addition of calcium, the peptide forms a beta helix secondary structure. We have designed two variations of our beta roll domain. First, we have mutated one face of the beta roll domain to contain leucine residues so that the calcium-dependent structural formation leads to dimerization through hydrophobic interactions. Second, an α-helical leucine zipper domain is appended to the engineered beta roll domain as an additional means of forming intermolecular cross-links. This full peptide construct forms a hydrogel only in calcium-rich environments. The resulting structural and mechanical properties of the supramolecular assemblies are compared with the wild-type domain using several biophysical techniques including circular dichroism, FRET, bis-ANS binding and microrheology. The calcium responsiveness and rheological properties of the leucine beta roll containing construct confirm the potential of this allosterically regulated scaffold to serve as a cross-linking domain for stimulus-responsive biomaterials development.

Abstract
Leucine zipper sequences have been widely used to engineer protein-based hydrogels for biomedical applications. Previously, we have used this method to engineer tandem modular protein-based hydrogels as a step toward developing extracellular matrix-mimetic hydrogels. However, the spontaneous self-association of leucine zipper sequences in solution has made it challenging to express and purify tandem modular proteins carrying leucine zipper under native conditions. To obviate this problem, here we report a novel two-component approach to engineer tandem modular protein-based hydrogels. This methodology makes use of two complementary leucine zipper sequences (CCE and CCK), which do not self-associate but self-assemble into heterodimeric coiled-coils at neutral pH, as functional groups to drive the self-assembly of protein hydrogels. The two protein components are bifunctional and trifunctional tandem modular proteins carrying the leucine zipper functional groups. We found that the two proteins carrying CCE or CCK can be expressed and purified under native conditions with high yield. Upon mixing, the aqueous solution of the two proteins readily forms a transparent hydrogel. The resultant hydrogel can undergo reversible sol-gel transitions as a function of temperature, and shows much improved erosion properties. This method provides a new approach to tune the topology and physical properties of the protein hydrogels via genetic engineering, and opens the possibility to systematically explore the use of large native extracellular proteins to engineer extracellular matrix-mimetic hydrogels.

Abstract
Curcumin, a hydrophobic polyphenol, is an extract of turmeric root with antioxidant, anti-inflammatory and anti-tumorigenic properties. Its lack of water solubility and relatively low bioavailability set major limitations for its therapeutic use. In this study, a self-assembling peptide hydrogel is demonstrated to be an effective vehicle for the localized delivery of curcumin over sustained periods of time. The curcumin-hydrogel is prepared in-situ where curcumin encapsulation within the hydrogel network is accomplished concurrently with peptide self-assembly. Physical and in vitro biological studies were used to demonstrate the effectiveness of curcumin-loaded β-hairpin hydrogels as injectable agents for localized curcumin delivery. Notably, rheological characterization of the curcumin-loaded hydrogel before and after shear flow have indicated solid-like properties even at high curcumin payloads. In vitro experiments with a medulloblastoma cell line confirm that the encapsulation of the curcumin within the hydrogel does not have an adverse effect on its bioactivity. Most importantly, the rate of curcumin release and its consequent therapeutic efficacy can be conveniently modulated as a function of the concentration of the MAX8 peptide.

Abstract
Vitreoretinal disorders constitute a significant portion of treatable ocular disease. Advances in vitreoretinal surgery have included the development and characterization of suitable substitutes for the vitreous. Air, balanced salt solutions, perfluorocarbons, expansile gases, and silicone oil serve integral roles in modern vitreoretinal surgery. Vitreous substitutes vary widely in their properties, serve different clinical functions, and present different shortcomings. Permanent vitreous replacement has been attempted with collagen, hyaluronic acid, hydroxypropylmethylcellulose, and natural hydrogel polymers. None, however, have proven to be clinically viable. A long-term vitreous substitute remains to be found, and recent research suggests promise in the area of synthetic polymers. Here we review the currently available vitreous substitutes, as well those in the experimental phase. We classify these compounds based on their functionality, composition, and properties. We also discuss the clinical use, advantages, and shortcomings of the various substitutes. In addition we define the ideal vitreous substitute and highlight the need for a permanent substitute with long-term viability and compatibility. Finally, we attempt to define the future role of biomaterials research and the various functions they may serve in the area of vitreous substitutes.

Abstract
A highly stable biological film was prepared by casting an aqueous dispersion of protein and composite hydrogel obtained from the polysaccharide Scleroglucan (Sclg) and borax as a cross-linking agent. Heme proteins, such as hemoglobin (Hb), myoglobin (Mb), and horseradish peroxidase (HRP), were chosen as model proteins to investigate the immobilized system. A pair of well-defined quasi-reversible redox peaks, characteristics of the protein heme FeII/FeIII redox couples, were obtained at the Sclg-borax/proteins films on pyrolytic graphite (PG) electrodes, as a consequence of the direct electron transfer between the protein and the PG electrode. A full characterization of the electron transfer kinetic was performed by opportunely modeling data obtained from cyclic voltammetry and square wave voltammetry experiments. The efficiency of our cross-linking approach was investigated by studying the influence of different borax groups percentage in the Sclg matrix, revealing the versatility of this hydrogel in the immobilization of redox proteins. The native conformation of the three heme proteins entrapped in the hydrogel films were proved to be unchanged, reflected by the unaltered Soret adsorption band and by the catalytic activity toward hydrogen peroxide (H2O2). The main kinetic parameters, such as the apparent Michaelis-Menten constant, for the electrocatalytic reaction were also evaluated. The peculiar characteristics of Sclg-borax matrix make it possible to find wide opportunities as proteins immobilizing agent for studies of direct electrochemistry and biosensors development.

Abstract
Here, we present two bifunctional protein building blocks that coassemble to form a bioelectrocatalytic hydrogel that catalyzes the reduction of dioxygen to water. One building block, a metallopolypeptide based on a previously designed triblock polypeptide, is electron-conducting. A second building block is a chimera of artificial alpha-helical leucine zipper and random coil domains fused to a polyphenol oxidase, small laccase (SLAC). The metallopolypeptide has a helix-random-helix secondary structure and forms a hydrogel via tetrameric coiled coils. The helical and random domains are identical to those fused to the polyphenol oxidase. Electron-conducting functionality is derived from the divalent attachment of an osmium bis-bipyrdine complex to histidine residues within the peptide. Attachment of the osmium moiety is demonstrated by mass spectroscopy (MS-MALDI-TOF) and cyclic voltammetry. The structure and function of the alpha-helical domains are confirmed by circular dichroism spectroscopy and by rheological measurements. The metallopolypeptide shows the ability to make electrical contact to a solid-state electrode and to the redox centers of modified SLAC. Neat samples of the modified SLAC form hydrogels, indicating that the fused alpha-helical domain functions as a physical cross-linker. The fusion does not disrupt dimer formation, a necessity for catalytic activity. Mixtures of the two building blocks coassemble to form a continuous supramolecular hydrogel that, when polarized, generates a catalytic current in the presence of oxygen. The specific application of the system is a biofuel cell cathode, but this protein-engineering approach to advanced functional hydrogel design is general and broadly applicable to biocatalytic, biosensing, and tissue-engineering applications.

Abstract
Single-chain antibodies (scFvs) are comprised of IgG variable light and variable heavy domains tethered together by a peptide linker whose length and sequence can affect antigen binding properties. The ability to modulate antigen binding affinity through the use of environmental triggers would be of great interest for many biotechnological applications. We have characterized the antigen binding properties of an anti-fluorescein scFv, 4D5Flu, containing stimulus-responsive short elastin-like peptide linkers and nonresponsive flexible linkers. Comparison of length-matched flexible and short elastin-like peptide linkers indicates that a stimulus-responsive linker can confer stimulus-responsive control of fluorescein binding. A linker length of either six or 10 amino acids proved to have the largest thermally induced response. Similar differences in binding free energy changes indicate a common underlying mechanism of thermal responsiveness. Contrary to the thermal behavior, the effect of salt, another elastin beta-turn-inducing stimulus, stabilized antigen binding in the six- and 10-amino-acid linkers such that elastin-like linkers became less stimulus-responsive as compared with flexible linkers. Again, the thermodynamic analysis indicates a common mechanism of salt responsiveness. Characterization of the room-temperature binding affinities and evidence indicating a dimeric state of the scFvs concomitantly suggest the major contribution to the stimulus-responsive behavior derives from the perturbation of interdomain associations, rather than the linker-constrained disruption of the intramolecular association. The ability to use stimulus-responsive peptide modules to exert a novel control over protein function will likely find application in the creation of allosteric antibodies and scFv-based biosensors, and as a platform to enable the evolution of new stimulus-responsive peptides.
