Summary: Protein-polymer conjugation is a useful approach to improve protein stability and performance, but polymer-polymer interactions can also affect the properties of polymer-modified proteins. This study demonstrates that by adjusting the ratio of polymers, the productivity of lipase can be optimized, although this may lead to a trade-off between activity and stability.

Summary: This study achieved efficient immobilization of Candida rugosa lipase on commercial macroporous resins, resulting in an efficient catalyst for the synthesis of phytosterol esters. A solvent-free strategy using oleic acid as the esterification reaction medium yielded a high yield of ester synthesis. This immobilization strategy provides new possibilities for the high-efficiency production of pine sterol esters and other food source nutrients.

Summary: The study successfully prepared a new support material for encapsulating Candida rugosa lipase by combining edible mushroom-derived CQDs and ZIF-8 crystals, with higher enzyme loading efficiency compared to in-situ encapsulation. Structural, morphological, and spectrophotometric analyses showed that CQDs and the enzyme were physically entrapped within the three-dimensional structures of ZIF-8.

Summary: This study investigated the immobilization of Candida Rugosa lipase (CRL) on Ca doped Kit-6 solid through adsorption. The effects of various experimental parameters on the adsorption of CRL were studied. It was found that 0.5Ca/Kit-6 showed the highest CRL immobilization capacity and stability. In the transesterification of coconut oil to biodiesel, the CRL/0.5Ca/Kit-6 catalyst exhibited better catalytic performance under weak basic conditions.

Summary: This study used molecular modeling approaches to investigate the interaction between CRL and the specific MOF ZIF-8. The results of molecular docking analysis showed that ZIF-8 was located at the active site pocket of CRL and formed hydrogen bonds with specific amino acids. The MD simulation analysis demonstrated the stability of the CRL-ZIF-8 docked complex and the maintenance of all interactions throughout the simulation. These findings contribute to the understanding of the molecular mechanisms and potential applications of immobilized CRL for various industries.

Summary: The study successfully produced biodiesel from tallow seed oil by codisplaying CRL1 and ROL on the cell surfaces of P. pastoris whole-cell catalysts. The activity of codisplaying strains was significantly higher than that of single-displayed enzymes, and using codisplayed enzymes for catalysis can increase the production of methyl esters.

Summary: This study developed a photoenzymatic platform for asymmetric catalysis by immobilizing wheat germ lipase (WGL) onto rationally designed photocatalytic porphyrinic covalent organic frameworks (COFs). The WGL@COFs photobiocatalysts demonstrated high enzymatic activity and good operational stability, and exhibited excellent performance for an enantioselective Mannich reaction under visible light irradiation. This work provides a general and efficient strategy for fabricating photobiocatalysts that enable highly efficient photoenzymatic asymmetric catalysis using COFs as photocatalytic platforms for enzyme immobilization.

Summary: Tyrosinases extracted and purified from commercial Agaricus bisporus protein extract and white mushrooms demonstrated high antiviral activity against hepatitis C virus. The newly discovered 50 kDa isoform showed even greater antiviral capacity than the well-known 45 kDa isoform. This antiviral activity was directly related to the enzymatic activity of tyrosinases.

Summary: Cu2O NPs were created in situ on graphene functionalized with Thermomyces lanuginosus lipase (G@TLL), acting as a template and binder, producing a heterogeneous catalyst. The G@TLL-Cu2O hybrid exhibited high catalytic capacity in the degradation of toxic organic compounds such as trichloroethylene (TCE) and Rhodamine B (RhB). The hybrid showed improved catalytic efficiency compared to the unsupported counterpart and successfully achieved complete degradation of RhB in the presence of H2O2.

Summary: In this study, nanostructured copper materials were designed and synthesized to produce efficient and sustainable copper bionanohybrids with catalytical and antimicrobial properties. Different quantities of a reducing agent were added during the synthesis, resulting in copper bionanohybrids with various metallic species, nanoparticles sizes, and structures. The antimicrobial activity of the bionanohybrids was evaluated against different strains of bacteria, with varying efficiencies observed depending on the bacterial strain and the percentage of reduction in the synthesis. Notably, the antimicrobial activity against Mycobacterium smegmatis was better with bionanohybrids synthesized with a lower reduction step.
