Abstract
We discuss the diverse functions of proteases in the context of their biotechnological and medical significance, as well as analytical approaches used to determine the functional activity of these enzymes. An insight into modern approaches to studying the kinetics and specificity of proteases, based on spectral (absorption, fluorescence), mass spectrometric, immunological, calorimetric, and electrochemical methods of analysis is given. We also examine in detail electrochemical systems for determining the activity and specificity of proteases. Particular attention is given to exploring innovative electrochemical systems based on the detection of the electrochemical oxidation signal of amino acid residues, thereby eliminating the need for extra redox labels in the process of peptide synthesis. In the review, we highlight the main prospects for the further development of electrochemical systems for the study of biotechnologically and medically significant proteases, which will enable the miniaturization of the analytical process for determining the catalytic activity of these enzymes.

[PMID: 33513990 PMCID: PMC7911952 DOI: 10.3390/nano11020334] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/03/2020] [Revised: 01/21/2021] [Accepted: 01/22/2021] [Indexed: 12/02/2022]
Abstract
In this study, a methodology utilizing peptide conformational imprints (PCIs) as a tool to specifically immobilize porcine pancreatic alpha-trypsin (PPT) at a targeted position is demonstrated. Owing to the fabrication of segment-mediated PCIs on the magnetic particles (PCIMPs), elegant cavities complementary to the PPT structure are constructed. Based on the sequence on targeted PPT, the individual region of the enzyme is trapped with different template-derived PCIMPs to show certain types of inhibition. Upon hydrolysis, N-benzoyl-L-arginine ethyl ester (BAEE) is employed to assess the hydrolytic activity of PCIMPs bound to the trypsin using high-performance liquid chromatography (HPLC) analysis. Further, the kinetic data of four different PCIMPs are compared. As a result, the PCIMPs presented non-competitive inhibition toward trypsin, according to the Lineweaver-Burk plot. Further, the kinetic analysis confirmed that the best parameters of PPT/PCIMPs 233-245+G were Vmax = 1.47 × 10-3 mM s-1, Km = 0.42 mM, kcat = 1.16 s-1, and kcat/Km = 2.79 mM-1 s-1. As PPT is bound tightly to the correct position, its catalytic activities could be sustained. Additionally, our findings stated that the immobilized PPT could maintain stable activity even after four successive cycles.

Covalent Immobilization of β-Glucosidase into Mesoporous Silica Nanoparticles from Anhydrous Acetone Enhances Its Catalytic Performance. NANOMATERIALS (BASEL, SWITZERLAND) 2020; 10:E108. [PMID: 31948120 PMCID: PMC7022324 DOI: 10.3390/nano10010108] [Citation(s) in RCA: 32] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/19/2019] [Revised: 12/10/2019] [Accepted: 12/30/2019] [Indexed: 01/09/2023]
Abstract
An immobilization protocol of a model enzyme into silica nanoparticles was applied. This protocol exploited the use of the bifunctional molecule triethoxysilylpropylisocyanate (TEPI) for covalent binding through a linker of suitable length. The enzyme β-glucosidase (BG) was anchored onto wrinkled silica nanoparticles (WSNs). BG represents a bottleneck in the conversion of lignocellulosic biomass into biofuels through cellulose hydrolysis and fermentation. The key aspect of the procedure was the use of an organic solvent (anhydrous acetone) in which the enzyme was not soluble. This aimed to restrict its conformational changes and thus preserve its native structure. This approach led to a biocatalyst with improved thermal stability, characterized by high immobilization efficiency and yield. It was found that the apparent KM value was about half of that of the free enzyme. The Vmax was about the same than that of the free enzyme. The biocatalyst showed a high operational stability, losing only 30% of its activity after seven reuses.

Abstract
Abstract
The objective of this review is to outline the crucial role that peptides play in various sectors, including medicine. Different ways of producing these compounds are discussed with an emphasis on the benefits offered by industrial enzyme biotechnology. This paper describes mechanisms of peptide bond formation using a range of proteases with different active site structures. Importantly, these enzymes may be further improved chemically and/or genetically to make them better suited for their various applications and process conditions. The focus is on extremophilic proteases, whose potential does not seem to have been fully appreciated to date. The structure of these proteins is somewhat different from that of the common commercially available enzymes, making them effective at high salinity and high or low temperatures, which are often favorable to peptide synthesis. Examples of such enzymes include halophilic, thermophilic, and psychrophilic proteases; this paper also mentions some promising catalytic proteins which require further study in this respect.

Abstract
The aim of the study was to create a self-emulsifying drug delivery system (SEDDS) with mucolytic properties based on incorporated papain for improved mucus permeation. In order to increase the lipophilicity of the enzyme and to dissolve it in SEDDS, hydrophobic ion pairing with sodium deoxycholate in a molar ratio of 20:1 (surfactant: enzyme) was performed. The yield of precipitated papain was 86.8±2.7% and the ion pair was loaded into the formulations to 1% (m/m). Suitable formulations were chosen according to their properties to dissolve the ion pair and characterized regarding droplet size and polydispersity index. Prepared emulsions were in a droplet size range between 50 and 120nm. Enzyme activity assay of complex and loaded SEDDS was conducted to ensure proteolytic qualities for following permeation and diffusion studies. SEDDS loaded with the ion pair showed an almost 2-fold increase in mucus permeation compared to the control without complex. Furthermore, 3-fold enhanced mucus diffusion could be confirmed in a second assay and an increase of mucosal residence on porcine intestinal mucosa up to 3- and 5-fold was observed as against the blank formulations. Consequently the incorporation of enzymes exhibiting proteolytic properties in self-emulsifying drug delivery systems may be considered as a promising strategy to enhance mucus permeation and overcome intestinal barriers.

Abstract
Enzymes are used as biocatalysts in a vast range of industrial applications. Immobilization of enzymes to solid supports or their self-assembly into insoluble particles enhances their applicability by strongly improving properties such as stability in changing environments, re-usability and applicability in continuous biocatalytic processes. The possibility of co-immobilizing various functionally related enzymes involved in multistep synthesis, conversion or degradation reactions enables the design of multifunctional biocatalyst with enhanced performance compared to their soluble counterparts. This review provides a brief overview of up-to-date in vitro immobilization strategies while focusing on recent advances in enzyme engineering towards in situ self-assembly into insoluble particles. In situ self-assembly approaches include the bioengineering of bacteria to abundantly form enzymatically active inclusion bodies such as enzyme inclusions or enzyme-coated polyhydroxyalkanoate granules. These one-step production strategies for immobilized enzymes avoid prefabrication of the carrier as well as chemical cross-linking or attachment to a support material while the controlled oriented display strongly enhances the fraction of accessible catalytic sites and hence functional enzymes.
