AB  - Novel industrial biocatalysts are needed which can offer advantages over traditional chemical processes with respect to sustainability, process efficiency, and reduced negative impact on the environment. Implementation of either native or mutated enzymes for various industrial applications is currently limited due to a lack of protein stability in harsh conditions. Metal-organic frameworks (MOFs), known for their ultra-high porosity and crystallinity, are perfect host materials that can protect guest enzymes from inhospitable external environments. Herein we show that the surface charge and chemistry of a protein determine its ability to seed MOF growth. We demonstrate that chemical modification of carbohydrate parts on the protein surface is an effective method for controlling biomimetic mineralization by zeolitic imidazolate framework-8 (ZIF-8). Protein charge, mixing of reactants, and stirring speed have been demonstrated to play important roles in controlling biomineralization reaction rate, particle shape, and morphology. This study highlights the important role played by protein surface chemistry in encapsulation and outlines a general method for facilitating the biomimetic mineralization of glycoproteins.

AB  - The durability of enzymes in harsh conditions can be enhanced by immobilization within metal-organic frameworks
(MOFs) via a process called biomimetic mineralisation. Zeolitic imidazolate framework-8 (ZIF-8) is widely used as a
protective coating to encapsulate proteins. The formation of nucleation centres and further biocomposite particle
growth is entirely governed by the pure electrostatic interactions between the protein’s surface and positively charged
Zn(II) metal ions. It was previously shown that enhancing these electrostatic interactions by a chemical modification
of surface amino acid residues can lead to a rapid biocomposite formation. However, a chemical modification of
carbohydrate components by periodate oxidation for glycoproteins can serve as an alternative strategy. In the present
study, an industrially important enzyme glucose oxidase (GOx) was selected as a model system. Periodate oxidation
of GOx by 2.5 mM sodium periodate increased negative charge on the enzyme molecule. Biomineralization
experiments with oxidized GOx resulted in higher specific activity, effectiveness factor, and higher thermostability of
the ZIF-8 biocomposites.

AB  - Many articles in the literature deal with horseradish peroxidase (HRP) biomineralization, but none pay attention to the isoenzyme composition of commercial HRP or the influence of the carbohydrate component of the protein molecule on the biomineralization process. To study the impact of these factors, we performed periodate oxidation of commercial HRP and a purified HRP-C isoform for biomineralization within ZIF-8. With purified HRP, enzyme@ZIF-8 biocomposites with higher activity were obtained, while periodate oxidation of the carbohydrate component of both commercial HRP and purified HRP-C yields biocomposites with very high activity in acetate buffer that does not degrade the ZIF-8 structure. Using acetate instead of phosphate buffer can prevent the false high activity of HRP@ZIF-8 biocomposites caused by the degradation of ZIF-8 coating. At the same time, purification and especially oxidation of the carbohydrate component of enzymes prior to biomineralization lead to significantly improved activity of the biocomposites.

AB  - Metal-organic frameworks (MOFs) are a class of materials well-known for their high degree of crystallinity and
ultrahigh porosity. Modular synthesis from organic linkers and metal nodes allows for precise control of structure,
pore size and chemical functionality of MOFs. Recently, MOFs have been explored for their potential to form novel
biocomposites with proteins by a process termed biomimetic mineralization. These novel MOF biocomposites show
great promise for application to industrial biocatalysis where strategies for enhancing enzyme stability are of
significant interest. The protective capacity and applications of biomimetically mineralized biomacromolecule zeolitic
imidazolate framework (ZIF-8) composites are likely dependent on the charge of the biomolecule and the topology
of the mineralized ZIF-8 coating. Herein, we identify conditions to reliably yield the porous periodate oxidized
horseradish peroxidase@ZIF-8 sodalite topology biocomposite in preference to other more dense phases.

AB  - Enzyme immobilization enables maintenance of enzyme activity and structural stability even in adverse conditions 1. Structural changes in enzymes that can occur due to the action of organic solvents, inhibitors or increased temperature can be prevented by immobilization of the enzymes in metal–organic frameworks (MOFs). It is reported that several enzymes, such as cytochrome c and horseradish peroxidase (HRP) have been successfully incorporated into MOFs 2. The aim of this work is to produce wild type horseradish peroxidase, isoform C1A, and several mutants specially designed to increase the activity and stability of HRP while immobilized within selected MOFs. Wild type and its variants were produced in metalotrophic yeast, Pichia pastoris KM71H strain, their activity and basic kinetic parameters were determined and compared prior imobilization.

AB  - Glucose oxidase (GOx) is an enzyme that belongs to a group of oxidoreductases. This enzyme catalyzes the oxidation of glucose to gluconic acid using molecular oxygen as an electron acceptor. Glucose oxidase contains carbohydrates in its structure, most often mannose and glucose (11-13%) 1. Durability of GOx in harsh conditions can be enhanced by encapsulation within metal–organic frameworks via a process called biomimetic mineralisation. We demonstrate that chemical modification of carbohydrate parts on the protein surface by periodate oxidation is an effective method for control of biomimetic mineralisation by zeolitic imidazolate framework-8 (ZIF-8). Obtained GOx-ZIF-8 biocomposite had the higher half-life at 65oC, and higher specific activity than native GOx.

AB  - Enzymes as industrial biocatalysts offer numerous advantages over traditional chemical processes
concerning sustainability and process efficiency. Immobilization of enzymes on solid supporters is
one of the key strategies for improving the practical performances of enzymes.
Metal-organic frameworks (MOFs) are promising candidates for enzyme immobilization. MOFs are
porous coordination polymers consisting of metal-containing nodes and organic ligands linked
through coordination bonds. It has been demonstrated that proteins can be successfully immobilized
even in MOF pores whose apertures are smaller than the molecular dimension of the protein due to its
conformational flexibility.
For our study, we selected horseradish peroxidase (HRP) encapsulated in MOF PCN-888(Al). We
report the modelling of PCN-888(Al) MOF and the design of novel HRP mutants, which determine
their enzymatic activity and magnitude of intermolecular interactions with MOF. Using a combined
in silico approach, consisting of Informational Spectrum Method (ISM) bioinformatics method,
molecular docking and molecular dynamics simulations, we propose new HRP mutants, which show
higher/lower specific catalytic activity and higher/lower MOF-HRP dissociation constant, compared
to the wild type of enzyme.

AB  - Metal-organic frameworks (MOFs) are a class of inorganic materials with potential application in gas adsorption, biosensitization, biocatalysis, and drug delivery [1]. Zeolitic imidazolate frame-works (ZIFs) are a subclass of MOFs, particularly suitable for enzyme immobilization by biomi-metic mineralization [1]. ZIF-8 consisting of tetrahedral Zn(II) ions bridged via 2-methylimidazole ligands (mIM) is most commonly used for this purpose. However, the topology and morphology of ZIF-8 crystals vary depending on the experimental synthesis conditions. In addition, during the process of biomimetic mineralization, the biocomposite composed of the enzyme immobilized in ZIF-8 is washed with buffers and detergents to remove excess of an adsorbed enzyme, which can lead to the chemical transformation of the surface and undesirable release of the enzyme. There-fore, the influence of anion nature on the topology and morphology of ZIF-8 was investigated in this work, and the stability of ZIF-8 crystallites was tested in acetate buffer (0.1 M; pH = 5.5) and sodium dodecyl sulfate solution (ω = 10%). Crystal morphology was monitored by scanning elec-tron microscopy, while topology was determined using powder X-ray diffraction.

AB  - Pectins are a group of heterologous polysaccharides capable of forming hydrogels and applicable in many industrial processes. A new type of modified pectin was synthesized by periodate oxidation and reductive amination with dopamine and sodium cyanoborohydride. The success of modification was confirmed by UV–Vis,FTIR, and 1H NMR spectroscopy. The obtained dopamine-pectin could form hydrogels by ionic crosslinking of carboxyl groups with calcium or by crosslinking phenol groups with laccase. For enzymatic crosslinking with laccase from Streptomyces cyaneus expressed in E. coli, isolation and purification of the enzyme was done. Using emulsion-based enzymatic crosslinking polymerization, dopamine-pectin microbeads with immobilized laccase were made. The immobilized laccase showed improved thermal and pH stability in comparison to the free enzyme. The immobilized biocatalyst effectively decolorized various dyes: Amido Black 10B, Reactive Black 5, and Evans Blue. After ten cycles of repeated use, the microbead immobilized laccase could still decolorize 60% and 36% of Amido Black 10B and Reactive Black 5, respectively.
