Abstract
Papain is useful for the enzymatic digestion of various proteins to produce functional peptides or protein fragments. Immobilized papain being reactive toward proteins and easily removable from a reaction mixture is worth developed. In the present work, liposomes were applied as colloidal carriers of papain for the catalytic digestion of polyclonal immunoglobulin G (IgG). Papain was covalently conjugated at pH = 7.0 via tris-succinimidyl aminotriacetate (TSAT) to liposomes incorporated with 5 mol % poly(ethylene glycol)-tethered lipid with a reactive amino group. The papain-conjugated liposome (liposome-papain) catalyzed the hydrolysis of Nα-benzoyl-l-arginine 4-nitroanilide hydrochloride (BAPNA) at pH = 5.0-7.0. The activity of liposome-papain significantly increased with increasing temperature from 25 to 50 °C. The Michaelis constant Km was determined with respect to the liposome-papain- and free papain-catalyzed reactions with BAPNA at 37 °C as Km = 1.11 ± 0.13 and 11.6 ± 2.9 mM, respectively. Liposome-papain was applied to the catalytic digestion of 10 mg·mL-1 IgG at 37 °C for 24 h at pH = 5.0-7.0. The reaction mixture could be analyzed without pretreatment by using the affinity columns immobilized with the protein A or protein L ligand because colloidal liposome-papain quickly flowed through the chromatographic stationary phase, exhibiting little proteolytic effect on the proteinaceous ligands. The analysis clearly demonstrated the catalytic production of antigen-binding fragments (Fab) from IgG in an enzyme concentration- and pH-dependent manner. Liposome-papain with 15 or 50 mol % anionic lipids also catalyzed the formation of Fab from IgG. The above results demonstrated that liposome-papain was useful to digest IgG and to purify Fab formed with the affinity chromatography.

Abstract
This study aimed to fabricate gum Arabic (GA)-coated Fe3O4 nanoparticles bearing numerous active aldehyde groups on their surface, followed by an assessment of their capability as a magnetic support for the covalent immobilization of the trypsin enzyme for the first time. FT-IR, XRD, TGA, and SEM results demonstrated the successful synthesis of GA-coated Fe3O4 nanoparticles, along with the covalent immobilization of the enzyme onto the support. Immobilization enhanced the relative enzymatic activity across a range of aqueous solution pH levels (ranging from 4 to 11) and temperatures (ranging from 20 to 80 °C) without altering the optimum pH and temperature for trypsin activity. Kinetic studies using Michaelis-Menten plots revealed changes in kinetic parameters, including a lower Vmax and higher Km for immobilized trypsin compared to the free enzyme. The immobilization onto magnetic gum Arabic nanoparticles resulted in an improved stability of trypsin in the presence of various solvents, maintaining a stability order comparable to that of the free enzyme due to the stabilizing effect of the support. The reusability results showed that the immobilized enzyme can retain over 93% of its activity for up to 15 cycles.

Abstract
Graphene quantum dots (GQDs) are a novel carbon nanomaterial from the graphene family due to their unique physicochemical properties and diverse range of applications. However, in terms of the sustainable utility of GQDs, their synthesis methods are the main roadblock because of their high production costs and the release of toxic byproducts during the production processes. Thus, the search for sustainable and economical fabrication methods for preparing GQDs is one of the most essential areas of research for their practical applications. In this context, lignocellulosic biomass (LCB) wastes are a prime choice for the fabrication of GQDs due to their high carbon and cellulose content, which are favorable for being employed as precursors and reducing agents Additionally, LCBs are a prime source of potential bioenergy production, which is currently a key research hotspot to combat environmental pollution, global warming, and energy crises. Therefore, the present review provides feasibility for sustainable and environmentally friendly fabrication of GQDs using LCB wastes for their possible utility in cellulosic biofuel production technology improvement. Furthermore, the prospective of using these GQDs as catalysts in bioenergy production for the development of low-cost biomass-based biofuel production technology has been discussed along with the existing limitations and their sustainable recommendation.

Proteases immobilized on nanomaterials for biocatalytic, environmental and biomedical applications: Advantages and drawbacks. Biotechnol Adv 2024; 70:108304.

Abstract
Proteases have gained significant scientific and industrial interest due to their unique biocatalytic characteristics and broad-spectrum applications in different industries. The development of robust nanobiocatalytic systems by attaching proteases onto various nanostructured materials as fascinating and novel nanocarriers has demonstrated exceptional biocatalytic performance, substantial stability, and ease of recyclability over multiple reaction cycles under different chemical and physical conditions. Proteases immobilized on nanocarriers may be much more resistant to denaturation caused by extreme temperatures or pH values, detergents, organic solvents, and other protein denaturants than free enzymes. Immobilized proteases may present a lower inhibition. The use of non-porous materials in the immobilization prevents diffusion and steric hindrances during the binding of the substrate to the active sites of enzymes compared to immobilization onto porous materials; when using very large or solid substrates, orientation of the enzyme must always be adequate. The advantages and problems of the immobilization of proteases on nanoparticles are discussed in this review. The continuous and batch reactor operations of nanocarrier-immobilized proteases have been successfully investigated for a variety of applications in the leather, detergent, biomedical, food, and pharmaceutical industries. Information about immobilized proteases on various nanocarriers and nanomaterials has been systematically compiled here. Furthermore, different industrial applications of immobilized proteases have also been highlighted in this review.

Mol Biotechnol 2023; 65:1809-1823. [PMID: 36795275 DOI: 10.1007/s12033-023-00687-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2022] [Accepted: 02/02/2023] [Indexed: 02/17/2023]
Abstract
The immobilized enzymes' properties can be affected by cross-linkers on the surface of supports. To study how cross-linkers alter enzymes function, chitosan-coated magnetic nanoparticles (CMNPs) with immobilized papain were prepared using glutaraldehyde and or genipin, and then, the properties of the nanoparticles and the immobilized enzymes were assessed. The Scanning Electron Microscope (SEM), Fourier Transform Infrared (FTIR), and X-Ray Diffraction (XRD) results showed that the CMNPs were prepared and papain molecules were immobilized on CMNPs by glutaraldehyde (CMNP-Glu-Papain) or by genipin (CMNP-Gen-Papain). Also, the results associated with enzymes activity indicated that the immobilization by glutaraldehyde and genipin increased the pH optimum of papain from 7 to 7.5 and 9, respectively. The kinetic results indicated that the immobilization by genipin slightly affects the enzyme affinity to the substrate. The stability results showed that CMNP-Gen-Papain has more thermal stability than CMNP-Glu-Papain and papain immobilization on CMNPs by genipin leads to stabilization of the enzyme in the presence of polar solvents, probably due to the more hydroxyl groups on CMNPs activated by genipin. In conclusion, this study suggests that there is a relationship between the types of cross-linker on the surface of supports, and the mechanism of action, kinetic parameters, and the stability of immobilized papain.

Abstract
Papain, as a classical cysteine protease, has been widely used in the food, pharmaceutical, chemical, and cosmetic fields. However, there are few information about the peroxidase-like activity of papain catalyzed substrate to produce fluorescence. In this study, we found that papain can catalyze H2O2 to convert o-phenylenediamine (OPD), and generate fluorescence emission at 550 nm under 430 nm excitation. Based on this foundation, we report a papain/OPD/H2O2 system for fluorescence detection of uric acid. The method exhibits a wide linear range of 10-1000 μM with a limit-of-detection of 4.6 μM, and has been successfully used to detect uric acid in human serum. This study paves the way for the application of papain as catalyst for fluorescence detection of different target biomolecules, such as cholesterol, glucose, lactate, for which H2O2 is a product of oxidoreductase enzymes.
