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 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.
